#Emacs tip of the day: shortdoc-display-group. Amazing new built-in functionality!
By default a little empty, but it's a great way for creating your own "cheatsheet" lists as you learn more about Emacs / #elisp.
See attached screenshot for an example - here I started making a cheatsheet for date/time manipulation functions I've been researching recently.
I hope the core developers will soon recognize the utility for user-maintained shortdocs, and improve the interface a bit (e.g. give us a defcustom).
As an extra bonus, if a function was added to a shortdoc group, the built-in help will mention that group!
See another attached screenshot, showing how the help buffer for `time-convert' mentions my shortdoc group.
As more functions hopefully get their shortdoc entries, this will greatly aid discovery. It's potentially much more ergonomic than the options we had so far, namely:
- Finding the part of Info manual that mentions a function;
- Jumping to source and poking around.
