The fantastic magit mode in emacs (git integration) has text-based keyboard-driven menus that you interact with either by typing single letters (as shown in the screenshot) or by moving the text cursor over as specific option and pressing enter (which either takes you to another menu, performs an action, prompts you for some input or cycles a setting). The mouse also works, but its use is extremely rare. Is there any UX research into making GUIs keyboard-driven to the extent that the mouse becomes obsolete?

There's been a good bit of work on keyboard-driven interfaces over the years, and we're expecting to release something quite relevant to those questions within the next couple of weeks. 🙂 The interface in question borrows heavily from what's discussed in this thread, and moves on from there: https://twitter.com/jackrusher/status/1350839387500773378?s=20

@Jack Rusher can't wait for the release!

@Jack Rusher many thanks, I shall study the thread with great interest (also very interested in the release!)

@Mariano Guerra thanks!

Would that be interesting: https://blog.repl.it/clui

Took longer than expected because we tied the announcement into a conference talk, but here's the first part of the work I mentioned above 🙂 https://futureofcoding.slack.com/archives/CCL5VVBAN/p1624520177117600
