More likely, minor modes could be coupled to rigpa "modes", towers (sets of modes), or complexes (sets of towers), so that entering those modes/towers would enable those minor modes, and likewise disable the minor modes upon exiting. E.g. for Lisp editing, we might want to enable the symex / paredit minor mode in Lisp tower, and disable it upon swapping to Vim/Emacs tower. + +- Good question.

Totally intuitive. For > 3 it might be hard, so I think in practice you would alternate across more small towers rather than have fewer big towers - - Also, most modes are always available via "direct access" keybinding (eg. s-w = window mode), so you can jump to one at any time, and it'll return you to your original position in the tower when you exit. Modes don't need to be in the current tower in order for you to use them. But if you're using them frequently you might want to add them or temporarily switch to a tower that has them – whatever feels the most natural for the specific case. +- Bindings, no - it would be easier than currently because the bindings generally stay the same across modes (e.g. hjkl always means left down up right, and there are other conventions) +- Modes, if the tower is 2-3 tall, then it's not a problem at all.

This has always bugged me. Is there a "XModmap Mode"…? - - Vim users don't remap their keys. The homerow is not a big deal, actually. - - Hm… I've always found it a bit of an obstacle but haven't tried hard! hjkl → jk makes sense but hl, not so much. - - The day you want to do this, you'll absolutely be able to do it and have it become natural.

Can you give some examples, e.g. how can the user can use the concept of "mode of mode" to do some interesting editing? - - The more modes you have, the shorter the individual keystrokes become. - - ^ Not to be a pain but my comment about Dvorak is related :-) - - There are many bindings in Org mode (e.g. agenda manipulation, manipulating headings and subheadings, promoting/demoting) that would be a natural fit for a dedicated modal interface. At the moment you probably use only a subset of all of the available options because of the constraints of conveniently (1) knowing about, (2) remembering and (3) using the bindings. With a dedicated mode, you could edit Org buffers using a Vim-like modal interface where all of the options are easy to remember and use - - Mode mode / tower mode could be useful if you are doing literate programming or "multi-modal" org buffers where you have many different languages embedded within the Org file. In this case, you could modify your tower using mode mode, or swap between different towers, to quickly have the right modes for different parts of the file +- The more modes you have, the shorter the individual keystrokes become. + - ^ Not to be a pain but my comment about Dvorak is related :-) +- There are many bindings in Org mode (e.g. agenda manipulation, manipulating headings and subheadings, promoting/demoting) that would be a natural fit for a dedicated modal interface.

How do you deal with the explosion of the number of modes? - - This is a great question, so here is a long answer: - - I am keen to keep this extension lightweight so that it plays well with existing Emacs tools without needing a custom ecosystem. The modal interface abstraction layer "chimera" would be a big part of this, enabling existing modal-like interfaces to be recognized in the framework out of the box, meaning that they would be automatically "wired into" the broader framework via the standard exits (e.g. Escape and Enter) - - I'm not sure what the best way to handle dired would be, but if it could be handled in this way, then that would be the way to do it. - - The "complex" of towers initially available is tied to major mode, that takes away some of the complexity right off the bat. E.g. when you open a Lisp file it gives you a Lisp-related + general-purpose complex of towers - - The idea is to support the "explosion" of modes, but make it scale well by (1) having them be structured, and (2) the structure being the same at every level +- This is a great question, so here is a long answer: + - I am keen to keep this extension lightweight so that it plays well with existing Emacs tools without needing a custom ecosystem.

While this simplifies the actual editing process by defining them as a single set of keybindings, the complexity is transferred to navigating modes. - - While the complexity is transferred, the nature of that complexity is different. In the case of keybindings, the complexity is unstructured and ad hoc, whereas in the case of mode navigation, it's a matter of "going to the right place" for your keys to have the right meaning - - In practice you would only have towers of size 2-3 I would guess, with every other mode jump always being available via an ad hoc jump (e.g. even in Vim tower, you can always jump to Window mode and it would return you to the original mode you were in upon exit) - - And the main paradigm would be swapping between small towers +- While the complexity is transferred, the nature of that complexity is different.
