Description of the bug

Many people (like 5 so far?) have reported that they could not find out the keyboard shortcuts, and several resorted to source-diving. For example, see jj-vcs/jj#2951

The keyboard shortcuts are actually discoverable if you use the mouse to click the menu bar items, but 1) it never occurs to many people and 2) using the mouse may not even be an option for many.

Expected behavior

Ideal behavior would probably be a command palette widget. An indefinitely-usable workaround would be to pop up some kind of help page when pressing ?.

Actual behavior

You have to use the mouse or source-dive or simply despair.
