+# Local File History Possibilities in Emacs

+
+Emacs offers a myriad of ways to keep track of previous versions
+of your document: through tilde-like backup files, auto-save
+files, and of course the extensive built-in undo history
+system. Navigating that can be a chore unless you install
+something like vundo to visualize the undo tree. But with a huge
+undo-limit, even vundo can become unwieldy. What if we can conjure
+up a way to diff between the current document and the state it was
+in ten or twenty minutes ago, not unlike IntelliJ's local history
+system? Using a combination of Consult (preview) and diff-buff,
+that can be easily done! In this lightning talk, we'll explore how
+to quickly browse through diff history and roll back using
+built-in Emacs tooling.
