+WEBVTT - EmacsConf 2022, Ramin Honary: "Build a Zettelkasten with the Hyperbole Rolodex" captioned by ramin
+
+00:00:00.000 --> 00:00:06.759
+Hello, attendees of EmacsConf 2022!
+
+00:00:06.760 --> 00:00:08.839
+The title of my talk is:
+
+00:00:08.840 --> 00:00:16.159
+"Build a Zettelkasten with the Hyperbole Rolodex."
+
+00:00:16.160 --> 00:00:17.479
+My name is Ramin Honary.
+
+00:00:17.480 --> 00:00:19.279
+I work as a software engineer
+
+00:00:19.280 --> 00:00:22.839
+writing apps for a small machine learning consultancy.
+
+00:00:22.840 --> 00:00:24.839
+I have been using Emacs since roughly 2018
+
+00:00:24.840 --> 00:00:26.479
+after having switched from a workflow
+
+00:00:26.480 --> 00:00:29.439
+using Vim together with Screen/Tmux for over a decade.
+
+00:00:29.440 --> 00:00:31.439
+Today I'd like to talk a bit about
+
+00:00:31.440 --> 00:00:34.039
+the Hyperbole package for Emacs.
+
+00:00:34.040 --> 00:00:36.159
+Others are presenting talks later today
+
+00:00:36.160 --> 00:00:37.479
+about Hyperbole as well,
+
+00:00:37.480 --> 00:00:39.839
+including some of the the authors and maintainers,
+
+00:00:39.840 --> 00:00:41.879
+so I won't go into too much detail
+
+00:00:41.880 --> 00:00:43.559
+about how Hyperbole works.
+
+00:00:43.560 --> 00:00:45.039
+Instead, I want to present
+
+00:00:45.040 --> 00:00:46.839
+a more concrete use case for Hyperbole,
+
+00:00:46.840 --> 00:00:49.279
+which is how to use it to facilitate
+
+00:00:49.280 --> 00:00:51.919
+the Zettelkasten method.
+
+00:00:51.920 --> 00:00:53.759
+Most Emacs users will probably be
+
+00:00:53.760 --> 00:00:56.039
+more familiar with Org Roam.
+
+00:00:56.040 --> 00:00:58.679
+Org Roam may even be the first thing that comes to mind
+
+00:00:58.680 --> 00:01:00.399
+when you hear the word "Zettelkasten."
+
+00:01:00.400 --> 00:01:02.479
+But personally, I use Hyperbole
+
+00:01:02.480 --> 00:01:05.039
+because I found it easier to get started with
+
+00:01:05.040 --> 00:01:07.479
+using it as an ideas database.
+
+00:01:07.480 --> 00:01:09.599
+All you need to do is install the Hyperbole package
+
+00:01:09.600 --> 00:01:11.399
+(which is available on GNU-ELPA)
+
+00:01:11.400 --> 00:01:13.759
+and then set a few customization options.
+
+00:01:13.760 --> 00:01:15.399
+There is nothing else you really need to do
+
+00:01:15.400 --> 00:01:16.079
+to get started.
+
+00:01:16.080 --> 00:01:19.759
+And also, Hyperbole works nicely with Org Mode.
+
+00:01:19.760 --> 00:01:21.799
+So Hyperbole's built-in functionality
+
+00:01:21.800 --> 00:01:24.919
+can be used as a nice, light-weight alternative
+
+00:01:24.920 --> 00:01:28.199
+to other Emacs Zettelkasten packages.
+
+00:01:28.200 --> 00:01:30.599
+This talk is for people who are curious about
+
+00:01:30.600 --> 00:01:34.159
+getting started with the Zettelkasten method,
+
+00:01:34.160 --> 00:01:36.079
+but are not ready to commit
+
+00:01:36.080 --> 00:01:41.039
+to a more purpose-built solution like Org Roam.
+
+00:01:41.040 --> 00:01:42.719
+So the thing I'd like people
+
+00:01:42.720 --> 00:01:44.599
+to take away from this presentation
+
+00:01:44.600 --> 00:01:46.759
+is that the Hyperbole Emacs package
+
+00:01:46.760 --> 00:01:50.639
+provides you with a flat-file database called "HyRolo"
+
+00:01:50.640 --> 00:01:53.239
+which you can use to store ideas.
+
+00:01:53.240 --> 00:01:55.999
+Then you can use what Hyperbole calls "buttons"
+
+00:01:56.000 --> 00:01:57.239
+(which are hyperlinks)
+
+00:01:57.240 --> 00:02:00.519
+to execute arbitrary Emacs commands
+
+00:02:00.520 --> 00:02:03.159
+and by inserting links into your database
+
+00:02:03.160 --> 00:02:06.159
+that execute queries against the database itself.
+
+00:02:06.160 --> 00:02:08.959
+These query-action links serve as
+
+00:02:08.960 --> 00:02:10.319
+a means to link ideas together,
+
+00:02:10.320 --> 00:02:13.439
+thus creating a functioning "Zettelkasten."
+
+00:02:13.440 --> 00:02:15.479
+If this doesn't make sense to you,
+
+00:02:15.480 --> 00:02:19.839
+I'll explain what all of this means presently.
+
+00:02:19.840 --> 00:02:24.359
+So just a quick overview of what "Zettelkasten" is.
+
+00:02:24.360 --> 00:02:26.199
+Note that most of what I say
+
+00:02:26.200 --> 00:02:27.359
+about the Zettelkasten method
+
+00:02:27.360 --> 00:02:29.759
+comes from a guy called Sascha Fast,
+
+00:02:29.760 --> 00:02:33.119
+and his website: zettelkasten.de .
+
+00:02:33.120 --> 00:02:34.999
+So a Zettelkasten is, in brief,
+
+00:02:35.000 --> 00:02:38.199
+a database containing many nodes of interconnected ideas,
+
+00:02:38.200 --> 00:02:40.759
+each idea being a single quantity of knowledge
+
+00:02:40.760 --> 00:02:42.039
+(about a paragraph)
+
+00:02:42.040 --> 00:02:46.319
+and linked to other related ideas.
+
+00:02:46.320 --> 00:02:47.959
+Also, let me quickly mention
+
+00:02:47.960 --> 00:02:49.679
+that there are actually many tools I use
+
+00:02:49.680 --> 00:02:51.879
+that assist me with the zettelkasten method:
+
+00:02:51.880 --> 00:02:53.599
+Hyperbole for hyperlinks;
+
+00:02:53.600 --> 00:02:56.079
+Embark for general text editing;
+
+00:02:56.080 --> 00:02:57.279
+Org Mode for markup;
+
+00:02:57.280 --> 00:02:59.439
+Dired for managing large sets of files;
+
+00:02:59.440 --> 00:03:01.959
+Consult, Vertico, Orderless, Marginalia;
+
+00:03:01.960 --> 00:03:04.519
+for interactive search through directories and documents;
+
+00:03:04.520 --> 00:03:06.359
+and Magit for revision control,
+
+00:03:06.360 --> 00:03:08.159
+and syncing my database of ideas
+
+00:03:08.160 --> 00:03:10.199
+across a few of my computers.
+
+00:03:10.200 --> 00:03:12.959
+Each of these tools provides some unique functionality,
+
+00:03:12.960 --> 00:03:15.439
+but today I will be focusing mostly on Hyperbole
+
+00:03:15.440 --> 00:03:17.039
+and how it is especially useful
+
+00:03:17.040 --> 00:03:19.839
+for the task of linking information together
+
+00:03:19.840 --> 00:03:21.399
+which is the most important aspect
+
+00:03:21.400 --> 00:03:25.359
+of the Zettelkasten methodology.
+
+00:03:25.360 --> 00:03:28.399
+And now I'll briefly go over what Hyperbole is.
+
+00:03:28.400 --> 00:03:31.159
+At it's core, Hyperbole is a simple markup language
+
+00:03:31.160 --> 00:03:34.519
+specifically designed to markup hyperlinks.
+
+00:03:34.520 --> 00:03:38.439
+Now, a hyperlink usually is only able to jump to
+
+00:03:38.440 --> 00:03:40.959
+ordinary URLs and file paths.
+
+00:03:40.960 --> 00:03:44.319
+Hyperbole extends the function of a hyperlink to provide
+
+00:03:44.320 --> 00:03:45.999
+a simple human-readable markup
+
+00:03:46.000 --> 00:03:49.639
+for executing Emacs commands (called "button actions")
+
+00:03:49.640 --> 00:03:52.359
+and then, on top of this core functionality,
+
+00:03:52.360 --> 00:03:53.239
+a few mini applications
+
+00:03:53.240 --> 00:03:56.839
+for example "HyRolo" and "Koutline",
+
+00:03:56.840 --> 00:04:00.959
+have been built to make Hyperbole more generally useful
+
+00:04:00.960 --> 00:04:03.519
+as a personal information management tool.
+
+00:04:03.520 --> 00:04:07.959
+"HyRolo" is the feature that I use as my Zettelkasten,
+
+00:04:07.960 --> 00:04:10.999
+and in particular, the HyRolo search feature
+
+00:04:11.000 --> 00:04:12.319
+in combination with
+
+00:04:12.320 --> 00:04:16.719
+the usual Hyperbole hyperlink markup language.
+
+00:04:16.720 --> 00:04:19.199
+So let me just quote the Hyperbole manual:
+
+00:04:19.200 --> 00:04:24.759
+"Hyperbole includes HyRolo for convenient management of
+
+00:04:24.760 --> 00:04:27.439
+hierarchical, record-oriented information.
+
+00:04:27.440 --> 00:04:30.879
+Most often, this is used for contact management
+
+00:04:30.880 --> 00:04:33.519
+but it can quickly be adapted to most any
+
+00:04:33.520 --> 00:04:37.199
+record-oriented lookup task requiring fast retrieval."
+
+00:04:37.200 --> 00:04:38.839
+So in other words, for example,
+
+00:04:38.840 --> 00:04:41.399
+it can be used to run search queries
+
+00:04:41.400 --> 00:04:44.679
+across the full set of nodes in a set of Org-Mode files.
+
+00:04:44.680 --> 00:04:47.679
+This means we can use an Org-Mode file
+
+00:04:47.680 --> 00:04:49.639
+as a flat-file database
+
+00:04:49.640 --> 00:04:52.159
+in which entries in the database can be linked together.
+
+00:04:52.160 --> 00:04:55.239
+This, in essence, is a what a Zettelkasten is.
+
+00:04:55.240 --> 00:04:58.959
+HyRolo needs almost no configuration,
+
+00:04:58.960 --> 00:05:00.239
+even if you are using it
+
+00:05:00.240 --> 00:05:01.719
+for the purpose of Zettelkasten,
+
+00:05:01.720 --> 00:05:03.839
+but you should at least make sure
+
+00:05:03.840 --> 00:05:05.599
+you set the location of the database
+
+00:05:05.600 --> 00:05:08.159
+in your Emacs config file, using the Customize system
+
+00:05:08.160 --> 00:05:10.359
+or however you prefer to configure your Emacs.
+
+00:05:10.360 --> 00:05:13.799
+I use "use-package", and on this slide I have here
+
+00:05:13.800 --> 00:05:15.879
+an abridged version of what my "init.el" file
+
+00:05:15.880 --> 00:05:18.199
+looks like for the Hyperbole package.
+
+00:05:18.200 --> 00:05:21.159
+A few relevant environment variables are set:
+
+00:05:21.160 --> 00:05:23.879
+the "hyrolo-file-list" variable
+
+00:05:23.880 --> 00:05:26.919
+selects where to find Rolo database files
+
+00:05:26.920 --> 00:05:29.279
+for the purpose of search. I have it set
+
+00:05:29.280 --> 00:05:31.919
+to just the Zettelkasten flat file database.
+
+00:05:31.920 --> 00:05:35.199
+And I also set "hyrolo-date-format" variable.
+
+00:05:35.200 --> 00:05:37.879
+Each database entry has a time stamp, and
+
+00:05:37.880 --> 00:05:40.239
+I use the time stamp as a unique ID
+
+00:05:40.240 --> 00:05:43.279
+for each entry (that is, each idea node)
+
+00:05:43.280 --> 00:05:44.279
+in the database.
+
+00:05:44.280 --> 00:05:48.199
+Finally, before I get into the actual demo,
+
+00:05:48.200 --> 00:05:49.599
+let me quickly explain
+
+00:05:49.600 --> 00:05:51.559
+the Hyperbole mini-buffer menu system.
+
+00:05:51.560 --> 00:05:54.599
+Mini-buffer menus in Hyperbole work just like
+
+00:05:54.600 --> 00:05:55.559
+in an ordinary GUI,
+
+00:05:55.560 --> 00:05:58.759
+except you typically enter into the mini-buffer menu
+
+00:05:58.760 --> 00:06:01.159
+with a key binding instead of a mouse click.
+
+00:06:01.160 --> 00:06:03.319
+To open the Hyperbole menu,
+
+00:06:03.320 --> 00:06:06.479
+you use the Hyperbole universal leader key
+
+00:06:06.480 --> 00:06:09.519
+that's C-h h, which by the way,
+
+00:06:09.520 --> 00:06:13.239
+this rebinds the "view-hello-file" command,
+
+00:06:13.240 --> 00:06:15.759
+which is a command that probably most people never use.
+
+00:06:15.760 --> 00:06:20.919
+So all Hyperbole menu key sequences begin with C-h h.
+
+00:06:20.920 --> 00:06:23.239
+Please remember this:
+
+00:06:23.240 --> 00:06:25.159
+as I explain how to do things,
+
+00:06:25.160 --> 00:06:26.959
+please don't worry too much
+
+00:06:26.960 --> 00:06:28.679
+about the key sequences I use
+
+00:06:28.680 --> 00:06:30.319
+to perform certain actions.
+
+00:06:30.320 --> 00:06:32.319
+Really, I am just navigating
+
+00:06:32.320 --> 00:06:33.479
+the Hyperbole mini-buffer menus.
+
+00:06:33.480 --> 00:06:37.599
+It is a very discoverable and fluid user interface.
+
+00:06:37.600 --> 00:06:42.159
+Anyway, now that we have configured our Rolo database,
+
+00:06:42.160 --> 00:06:45.399
+let's see how we enter new ideas into the database.
+
+00:06:45.400 --> 00:06:48.879
+And I will start with an empty database,
+
+00:06:48.880 --> 00:06:53.639
+then I'll switch over to a more complete database
+
+00:06:53.640 --> 00:06:57.039
+that I prepared for this demo. So...
+
+00:06:57.040 --> 00:07:04.159
+first we type the Hyperbole universal leader key C-h h,
+
+00:07:04.160 --> 00:07:08.919
+and then, you can see the menus down here
+
+00:07:08.920 --> 00:07:15.279
+we type "r" for "Rolo" and "a" for "add".
+
+00:07:15.280 --> 00:07:19.479
+That's C-h h r a to enter a new idea.
+
+00:07:19.480 --> 00:07:23.319
+And this command is available globally so,
+
+00:07:23.320 --> 00:07:26.599
+much like with the "org-capture" feature in Org-Mode,
+
+00:07:26.600 --> 00:07:28.879
+you can run this command at any time,
+
+00:07:28.880 --> 00:07:32.479
+at the very moment you want to enter an idea.
+
+00:07:32.480 --> 00:07:36.159
+First we are prompted for an entry title,
+
+00:07:36.160 --> 00:07:38.799
+and if you were using HyRolo as a contact list,
+
+00:07:38.800 --> 00:07:40.959
+this is where you would enter the person's name.
+
+00:07:40.960 --> 00:07:43.199
+I am using it as a Zettelkasten,
+
+00:07:43.200 --> 00:07:45.439
+so I instead enter a title for my idea.
+
+00:07:45.440 --> 00:07:46.839
+I'll just type in...
+
+00:07:46.840 --> 00:07:53.159
+and as soon as I press enter after this prompt,
+
+00:07:53.160 --> 00:07:55.999
+my Zettelkasten org file is opened,
+
+00:07:56.000 --> 00:08:02.879
+a new entry with the timestamp is created,
+
+00:08:02.880 --> 00:08:06.319
+and the cursor is placed at this entry
+
+00:08:06.320 --> 00:08:09.079
+ready for me to enter the body text of the idea.
+
+00:08:09.080 --> 00:08:14.799
+I'll type that in...
+
+00:08:14.800 --> 00:08:18.039
+Now I save the "idea" file (C-x C-s)
+
+00:08:18.040 --> 00:08:20.879
+and switch back to what I was working on before
+
+00:08:20.880 --> 00:08:23.759
+with the usual C-x 0 (delete-window) command.
+
+00:08:23.760 --> 00:08:26.279
+Next, I'd like to talk about
+
+00:08:26.280 --> 00:08:28.719
+the HyRolo database search feature,
+
+00:08:28.720 --> 00:08:30.879
+which is very useful.
+
+00:08:30.880 --> 00:08:33.719
+The HyRolo search feature uses
+
+00:08:33.720 --> 00:08:35.319
+only Emacs built-in functions
+
+00:08:35.320 --> 00:08:36.599
+and there is no indexing
+
+00:08:36.600 --> 00:08:38.679
+as with tools like "mlocate" or Org-Roam.
+
+00:08:38.680 --> 00:08:41.439
+So far, I have not had any trouble with efficiency.
+
+00:08:41.440 --> 00:08:42.759
+I don't know if at some point in the future,
+
+00:08:42.760 --> 00:08:44.079
+it will start slowing down.
+
+00:08:44.080 --> 00:08:46.199
+Emacs built-in search functionality
+
+00:08:46.200 --> 00:08:47.679
+is already pretty efficient as it is.
+
+00:08:47.680 --> 00:08:50.839
+It could also be that I am in the habit
+
+00:08:50.840 --> 00:08:55.679
+of storing larger bodies of text in separate files,
+
+00:08:55.680 --> 00:08:57.559
+and not in the flat file database.
+
+00:08:57.560 --> 00:08:58.999
+Anyway, you can search
+
+00:08:59.000 --> 00:09:02.239
+by regex, by string, or by words.
+
+00:09:02.240 --> 00:09:03.799
+I personally find the string search
+
+00:09:03.800 --> 00:09:04.719
+to be the most useful.
+
+00:09:04.720 --> 00:09:07.479
+The difference between word search and string search
+
+00:09:07.480 --> 00:09:09.199
+is that string search provides
+
+00:09:09.200 --> 00:09:12.119
+logical query operators like AND, OR, XOR, and NOT.
+
+00:09:12.120 --> 00:09:14.199
+Once you run a search query,
+
+00:09:14.200 --> 00:09:16.479
+a "*HyRolo*" buffer is opened
+
+00:09:16.480 --> 00:09:18.159
+with the query's results.
+
+00:09:18.160 --> 00:09:20.439
+And this is a read-only-mode buffer
+
+00:09:20.440 --> 00:09:23.239
+with a few useful single-key action bindings
+
+00:09:23.240 --> 00:09:25.079
+for navigating the list of results
+
+00:09:25.080 --> 00:09:27.119
+which I will now demonstrate.
+
+00:09:27.120 --> 00:09:31.879
+By the way, I have now switched over
+
+00:09:31.880 --> 00:09:34.639
+to a larger example Rolo database that I have created
+
+00:09:34.640 --> 00:09:36.559
+to demonstrate more of the HyRolo features.
+
+00:09:36.560 --> 00:09:39.479
+The HyRolo search is available
+
+00:09:39.480 --> 00:09:40.679
+in the Hyperbole mini-buffer menu
+
+00:09:40.680 --> 00:09:42.239
+so it is always available to you.
+
+00:09:42.240 --> 00:09:46.959
+Start with the Hyperbole universal leader key C-h h
+
+00:09:46.960 --> 00:09:53.839
+then "r" for Rolo and "s" for search. That is C-h h r s.
+
+00:09:53.840 --> 00:09:56.039
+Now we are prompted for a search string:
+
+00:09:56.040 --> 00:10:02.519
+I type in "Alice Abelton", and when I press enter,
+
+00:10:02.520 --> 00:10:03.999
+the search results pop up
+
+00:10:04.000 --> 00:10:06.959
+and the number of results is printed in the mini-buffer.
+
+00:10:06.960 --> 00:10:09.599
+We could also enter a search expression
+
+00:10:09.600 --> 00:10:12.159
+similar to a Lisp S-expression
+
+00:10:12.160 --> 00:10:14.759
+with logical operators like AND or NOT,
+
+00:10:14.760 --> 00:10:19.279
+but you would not need to quote the search terms.
+
+00:10:19.280 --> 00:10:24.519
+So, for example (C-h h r s), I could write
+
+00:10:24.520 --> 00:10:30.279
+"(and university character)" within parentheses
+
+00:10:30.280 --> 00:10:31.959
+and this would find entries
+
+00:10:31.960 --> 00:10:33.799
+that only contain both of the words
+
+00:10:33.800 --> 00:10:35.759
+"university" and "character".
+
+00:10:35.760 --> 00:10:39.239
+For the most part, I only really ever use
+
+00:10:39.240 --> 00:10:41.719
+the ordinary string search without logical operators.
+
+00:10:41.720 --> 00:10:44.759
+So as you can see, a search result buffer
+
+00:10:44.760 --> 00:10:47.239
+called "*HyRolo*" has popped up
+
+00:10:47.240 --> 00:10:48.359
+with all of the matching entries.
+
+00:10:48.360 --> 00:10:51.319
+And the search results buffer is a read-only buffer
+
+00:10:51.320 --> 00:10:54.319
+with several useful navigation key bindings:
+
+00:10:54.320 --> 00:11:01.399
+I can press "o" to switch to "overview" mode,
+
+00:11:01.400 --> 00:11:03.959
+which shows all of the headings, but no content.
+
+00:11:03.960 --> 00:11:05.479
+This would include subheadings
+
+00:11:05.480 --> 00:11:07.959
+with like 2 stars in front of it or 3 stars
+
+00:11:07.960 --> 00:11:12.159
+I can press "a" to switch to "show all mode"
+
+00:11:12.160 --> 00:11:14.559
+which shows all of the content under each heading.
+
+00:11:14.560 --> 00:11:17.079
+If I know I am looking for a keyword
+
+00:11:17.080 --> 00:11:17.999
+in a top-level heading,
+
+00:11:18.000 --> 00:11:22.639
+I can press "t" to switch to the "top-level" view mode
+
+00:11:22.640 --> 00:11:25.439
+which shows only the top-level headings.
+
+00:11:25.440 --> 00:11:27.119
+As is always the case
+
+00:11:27.120 --> 00:11:28.879
+with the Emacs default key bindings,
+
+00:11:28.880 --> 00:11:32.359
+"n" and "p" move the cursor down and up lines,
+
+00:11:32.360 --> 00:11:34.519
+so I can navigate the cursor downward
+
+00:11:34.520 --> 00:11:37.599
+to an entry that looks interesting.
+
+00:11:37.600 --> 00:11:40.279
+I can press "s" to show the content
+
+00:11:40.280 --> 00:11:41.519
+of that particular entry.
+
+00:11:41.520 --> 00:11:44.799
+I can press "h" to hide the entry again.
+
+00:11:44.800 --> 00:11:49.479
+And I can press "e" or M-RET on the entry heading
+
+00:11:49.480 --> 00:11:53.279
+to "edit" that heading (that entry),
+
+00:11:53.280 --> 00:11:56.279
+which will open the Org-Mode file,
+
+00:11:56.280 --> 00:11:59.039
+that is, the Zettelkasten database file
+
+00:11:59.040 --> 00:12:01.759
+with the cursor at this particular entry.
+
+00:12:01.760 --> 00:12:07.639
+Be warned that editing an entry creates a new timestamp,
+
+00:12:07.640 --> 00:12:10.159
+which I do not need, and there is currently
+
+00:12:10.160 --> 00:12:12.039
+no way to avoid this behavior.
+
+00:12:12.040 --> 00:12:15.199
+I work around this by simply using the undo command
+
+00:12:15.200 --> 00:12:20.039
+which removes the unwanted timestamp.
+
+00:12:20.040 --> 00:12:25.559
+And so that is how I use the HyRolo search functionality.
+
+00:12:25.560 --> 00:12:31.999
+Now... since the most important aspect of Zettelkasten
+
+00:12:32.000 --> 00:12:33.839
+is linking ideas in the database,
+
+00:12:33.840 --> 00:12:37.039
+how do we actually make this work in HyRolo?
+
+00:12:37.040 --> 00:12:40.039
+So this is the secret sauce of Hyperbole,
+
+00:12:40.040 --> 00:12:41.119
+and the key take-away
+
+00:12:41.120 --> 00:12:43.279
+for this presentation (as I said earlier).
+
+00:12:43.280 --> 00:12:46.679
+Hyperbole provides markup syntax
+
+00:12:46.680 --> 00:12:50.079
+for executing arbitrary Emacs commands
+
+00:12:50.080 --> 00:12:53.759
+so you can link HyRolo entries together
+
+00:12:53.760 --> 00:12:56.039
+using the HyRolo search function.
+
+00:12:56.040 --> 00:12:58.279
+Let me demonstrate this now.
+
+00:12:58.280 --> 00:13:03.879
+I am back in my example HyRolo database,
+
+00:13:03.880 --> 00:13:06.239
+and if you take a closer look
+
+00:13:06.240 --> 00:13:11.399
+you can see some of the hyperlinks
+
+00:13:11.400 --> 00:13:13.119
+that I already created
+
+00:13:13.120 --> 00:13:15.839
+with the angle-round bracket syntax.
+
+00:13:15.840 --> 00:13:19.279
+Now with the cursor inside of these brackets,
+
+00:13:19.280 --> 00:13:23.439
+I can press M-RET to "click" on this link.
+
+00:13:23.440 --> 00:13:27.799
+As you can see, the search query
+
+00:13:27.800 --> 00:13:32.039
+corresponding to this hyperlink here has executed
+
+00:13:32.040 --> 00:13:34.919
+and popped up the "*HyRolo*" search results buffer.
+
+00:13:34.920 --> 00:13:38.719
+There is only one linked entry,
+
+00:13:38.720 --> 00:13:41.399
+but the list of ideas that are produced
+
+00:13:41.400 --> 00:13:43.759
+by the search query in this buffer here
+
+00:13:43.760 --> 00:13:45.639
+are the list of all of the other ideas
+
+00:13:45.640 --> 00:13:47.799
+that are related to this hyperlink
+
+00:13:47.800 --> 00:13:49.479
+that we just clicked on here.
+
+00:13:49.480 --> 00:13:52.199
+(Let me get rid of the other window...)
+
+00:13:52.200 --> 00:13:55.239
+Now from within this "*HyRolo*" buffer,
+
+00:13:55.240 --> 00:13:57.839
+I can navigate to another hyperlink...
+
+00:13:57.840 --> 00:14:03.759
+and clicking on that updates the "*HyRolo*" buffer
+
+00:14:03.760 --> 00:14:04.799
+with new results again.
+
+00:14:04.800 --> 00:14:10.119
+I can just keep navigating through
+
+00:14:10.120 --> 00:14:13.959
+all the Zettelkasten entries in this way.
+
+00:14:13.960 --> 00:14:18.639
+And so this is it.
+
+00:14:18.640 --> 00:14:22.719
+This is my simple but effective Zettelkasten,
+
+00:14:22.720 --> 00:14:25.119
+constructed entirely with the functionality
+
+00:14:25.120 --> 00:14:26.799
+already built-in to Hyperbole.
+
+00:14:26.800 --> 00:14:32.599
+In the remaining time,
+
+00:14:32.600 --> 00:14:36.999
+I'd like to talk about how Hyperbole hyperlinks work,
+
+00:14:37.000 --> 00:14:38.799
+because it's slightly different
+
+00:14:38.800 --> 00:14:40.759
+from how hyperlinks work in Org Mode
+
+00:14:40.760 --> 00:14:49.199
+or with the Emacs clickable text properties.
+
+00:14:49.200 --> 00:14:52.239
+The easiest way to create a hyperlink button
+
+00:14:52.240 --> 00:14:55.279
+that runs an Emacs command
+
+00:14:55.280 --> 00:14:59.479
+is simply to type the Emacs command as an S-expression,
+
+00:14:59.480 --> 00:15:03.399
+but with angle brackets instead of parentheses.
+
+00:15:03.400 --> 00:15:05.679
+If you were looking closely,
+
+00:15:05.680 --> 00:15:08.639
+you probably already saw a hyperlink of this form,
+
+00:15:08.640 --> 00:15:10.559
+an angle-bracketed Emacs command.
+
+00:15:10.560 --> 00:15:13.159
+This hyperlink simply calls
+
+00:15:13.160 --> 00:15:18.079
+the "hyrolo-fgrep" function with this string argument.
+
+00:15:18.080 --> 00:15:20.839
+and so clicking on this button
+
+00:15:20.840 --> 00:15:23.119
+is equivalent to running a HyRolo search
+
+00:15:23.120 --> 00:15:27.319
+with the C-h h r s key sequence.
+
+00:15:27.320 --> 00:15:31.399
+As you can see, clicking on it
+
+00:15:31.400 --> 00:15:32.919
+produced the search results
+
+00:15:32.920 --> 00:15:35.079
+for entries associated with that string query.
+
+00:15:35.080 --> 00:15:41.079
+It's also possible to label an action
+
+00:15:41.080 --> 00:15:43.599
+with a so-called "implicit link",
+
+00:15:43.600 --> 00:15:47.079
+and that's this angle-and-square bracketed notation.
+
+00:15:47.080 --> 00:15:51.999
+If I click on this button,
+
+00:15:52.000 --> 00:15:54.159
+it will activate this action
+
+00:15:54.160 --> 00:16:01.359
+to the right of the colon separator,
+
+00:16:01.360 --> 00:16:03.639
+and there are the relevant search results
+
+00:16:03.640 --> 00:16:04.679
+from that string query.
+
+00:16:04.680 --> 00:16:09.119
+Finally, there are "explicit links",
+
+00:16:09.120 --> 00:16:11.239
+which I find to be especially useful
+
+00:16:11.240 --> 00:16:12.599
+for the Zettelkasten method.
+
+00:16:12.600 --> 00:16:15.239
+I've already shown an example
+
+00:16:15.240 --> 00:16:17.079
+of using an explicit link before.
+
+00:16:17.080 --> 00:16:20.759
+What makes explicit links so useful is, firstly,
+
+00:16:20.760 --> 00:16:23.919
+that the button works with just the label alone.
+
+00:16:23.920 --> 00:16:26.599
+There is no need to write an S-expression or anything.
+
+00:16:26.600 --> 00:16:28.919
+You can write the link label
+
+00:16:28.920 --> 00:16:31.959
+inline with the body text of the idea.
+
+00:16:31.960 --> 00:16:34.879
+(For example, like this.)
+
+00:16:34.880 --> 00:16:38.999
+Explicit links are identified by their label,
+
+00:16:39.000 --> 00:16:40.839
+so they are especially good for
+
+00:16:40.840 --> 00:16:43.119
+the names of people and places.
+
+00:16:43.120 --> 00:16:46.399
+By the way, this Zettelkasten database is for
+
+00:16:46.400 --> 00:16:47.919
+a fictional story I started writing
+
+00:16:47.920 --> 00:16:50.079
+for the purpose of demonstrating HyRolo
+
+00:16:50.080 --> 00:16:52.879
+in this presentation, and I had so much fun writing it
+
+00:16:52.880 --> 00:16:54.999
+that I may actually continue developing this story.
+
+00:16:55.000 --> 00:16:58.639
+Anyway, let's create a new explicit link
+
+00:16:58.640 --> 00:17:01.679
+and a new idea entry for a character in the story.
+
+00:17:01.680 --> 00:17:10.239
+So suppose I want to create a new idea node entry
+
+00:17:10.240 --> 00:17:11.959
+for this fictional character here,
+
+00:17:11.960 --> 00:17:15.359
+and I'll also want to link this entry to that node.
+
+00:17:15.360 --> 00:17:17.839
+Since hyperlinks are just string search,
+
+00:17:17.840 --> 00:17:19.799
+we don't actually need to have
+
+00:17:19.800 --> 00:17:22.279
+an entry in the database for this character.
+
+00:17:22.280 --> 00:17:24.879
+The worst that can happen is that the hyperlink
+
+00:17:24.880 --> 00:17:27.319
+executes a search that returns no results.
+
+00:17:27.320 --> 00:17:29.079
+So it's OK to create the hyperlink
+
+00:17:29.080 --> 00:17:31.879
+before we have an actual entry for this person.
+
+00:17:31.880 --> 00:17:36.719
+(I'll just M-w copy the name.)
+
+00:17:36.720 --> 00:17:40.919
+Now I use the universal Hyperbole leader key C-h h,
+
+00:17:40.920 --> 00:17:44.519
+and then "e" for "explicit links"
+
+00:17:44.520 --> 00:17:49.359
+and "c" for "create". That's C-h h e c.
+
+00:17:49.360 --> 00:17:52.639
+We are prompted for an entry label
+
+00:17:52.640 --> 00:17:56.119
+but it defaults to the text highlighted by the region,
+
+00:17:56.120 --> 00:17:57.959
+so I just press enter.
+
+00:17:57.960 --> 00:18:00.479
+Now it prompts for a button type,
+
+00:18:00.480 --> 00:18:03.119
+so I select "hyrolo-fgrep"
+
+00:18:03.120 --> 00:18:06.479
+(and there's Orderless helping me go faster),
+
+00:18:06.480 --> 00:18:10.319
+and since "hyrolo-fgrep" requires
+
+00:18:10.320 --> 00:18:12.679
+a string argument for the search query,
+
+00:18:12.680 --> 00:18:14.479
+I am prompted for the query string.
+
+00:18:14.480 --> 00:18:21.839
+I'll type in "character:", (yank "Kerri Katz's" name)
+
+00:18:21.840 --> 00:18:26.839
+and there we are, the link has been created, and
+
+00:18:26.840 --> 00:18:31.159
+(let me just get rid of the # character)
+
+00:18:31.160 --> 00:18:32.719
+I can try it out.
+
+00:18:32.720 --> 00:18:36.199
+There's no search results. That's fine.
+
+00:18:36.200 --> 00:18:38.959
+We haven't created an idea entry yet
+
+00:18:38.960 --> 00:18:40.799
+for this character now.
+
+00:18:40.800 --> 00:18:43.399
+So let's go ahead and do that now.
+
+00:18:43.400 --> 00:18:45.679
+If we remember how to create a new idea,
+
+00:18:45.680 --> 00:18:52.359
+it's C-h h r a, and then I type "character:"
+
+00:18:52.360 --> 00:18:56.799
+and then yank the name again.
+
+00:18:56.800 --> 00:18:58.399
+Now a new node has been created,
+
+00:18:58.400 --> 00:19:04.359
+and I can start describing this character.
+
+00:19:04.360 --> 00:19:08.839
+Notice that I like to precede my characters
+
+00:19:08.840 --> 00:19:11.479
+with the keyword "character:" colon.
+
+00:19:11.480 --> 00:19:14.919
+This technique helps me to create hyperlinks
+
+00:19:14.920 --> 00:19:16.999
+using more descriptive search queries
+
+00:19:17.000 --> 00:19:19.879
+that return fewer but more useful search results.
+
+00:19:19.880 --> 00:19:23.839
+And finally, I can create an explicit link
+
+00:19:23.840 --> 00:19:26.039
+from this character back to
+
+00:19:26.040 --> 00:19:28.839
+the other character (her boyfriend).
+
+00:19:28.840 --> 00:19:31.159
+I just type in "<(Bertrand Becket)>",
+
+00:19:31.160 --> 00:19:37.039
+and this explicit link has already been created
+
+00:19:37.040 --> 00:19:39.679
+so I don't need to create it again. It just works.
+
+00:19:39.680 --> 00:19:41.879
+Hyperbole identifies buttons by their label,
+
+00:19:41.880 --> 00:19:44.719
+so as long as an explicit link button with that label
+
+00:19:44.720 --> 00:19:46.039
+has been created before,
+
+00:19:46.040 --> 00:19:51.079
+I just can type in the button with markup by hand,
+
+00:19:51.080 --> 00:19:53.279
+and then I can just use it.
+
+00:19:53.280 --> 00:19:57.839
+Now I am back to the search results
+
+00:19:57.840 --> 00:19:59.319
+for the boyfriend character.
+
+00:19:59.320 --> 00:20:04.159
+I hope you can see how minimal but useful
+
+00:20:04.160 --> 00:20:07.759
+is this particular Zettelkasten technique I have
+
+00:20:07.760 --> 00:20:10.559
+that uses this "HyRolo".
+
+00:20:10.560 --> 00:20:19.359
+I should also make clear that Hyperbole explicit links
+
+00:20:19.360 --> 00:20:22.279
+are encoded in a separate file in the same directory
+
+00:20:22.280 --> 00:20:24.279
+as the Zettelkasten flat-file database.
+
+00:20:24.280 --> 00:20:37.079
+(So, let's go back to that and C-x C-f ".hypb").
+
+00:20:37.080 --> 00:20:41.239
+You should not edit this file by hand,
+
+00:20:41.240 --> 00:20:43.599
+but it is human readable,
+
+00:20:43.600 --> 00:20:45.399
+so it works well with Git
+
+00:20:45.400 --> 00:20:47.079
+and other revision control systems.
+
+00:20:47.080 --> 00:20:49.559
+Whenever an explicit link is activated,
+
+00:20:49.560 --> 00:20:52.559
+it consults this file and runs the associated action,
+
+00:20:52.560 --> 00:20:55.839
+which, in the Zettelkasten use case,
+
+00:20:55.840 --> 00:20:58.799
+will always be to run a HyRolo search query.
+
+00:20:58.800 --> 00:21:02.039
+The advantage of keeping a separate table of links
+
+00:21:02.040 --> 00:21:03.919
+is that you can edit the link action
+
+00:21:03.920 --> 00:21:06.999
+(that is, the search query) in just one place,
+
+00:21:07.000 --> 00:21:10.559
+and the updated button action works everywhere
+
+00:21:10.560 --> 00:21:12.479
+without having to change any other files.
+
+00:21:12.480 --> 00:21:18.399
+So, that is all for today.
+
+00:21:18.400 --> 00:21:20.519
+Thank you so much for listening to my talk.
+
+00:21:20.520 --> 00:21:23.079
+I'll be available for questions
+
+00:21:23.080 --> 00:21:24.919
+for the next 20 minutes or so.
+
+00:21:24.920 --> 00:21:27.959
+If there are any questions that I cannot answer,
+
+00:21:27.960 --> 00:21:29.439
+you will have a chance to ask
+
+00:21:29.440 --> 00:21:31.799
+the author of Hyperbole himself, Bob Weiner,
+
+00:21:31.800 --> 00:21:34.239
+later today after his presentation.
+
+00:21:34.240 --> 00:21:43.920
+Thanks for your attention!
