Describe Key is a very simple IDA Pro plugin: invoke it, press a shortcut, and instantly see what actions are associated with the shortcut. Quick and easy, call it from anywhere in IDA.

Describe Key is a single-file IDAPython plugin with no external dependencies. As such, it should work on all platforms supported by IDA.

Simply copy describekey.py to your plugins directory and restart IDA.

(Alternatively, you could execute describekey.py as a script and call describekey.register_action() to load it manually)

From anywhere in IDA, press Alt-Shift-K to bring up the Describe Key dialog and press keys to your heart's content. Be enlightened as you discover all what those keys can do!

Press Esc to close the dialog.

Not being a Qt expert, I can't guarantee that the conversion from a Qt keypress event to an IDA shortcut is very robust. It is thus likely you might bump into some shortcuts that don't get recognized properly and give you the wrong (or no) action. Please let me know if you run into such a case.
