If you know the name of some command, but you’ve forgotten its keybinding(s) there are 3 common options to look the keybinding(s) up.
C-h f command-name
This will display some information about the command in question in a help buffer. Important bits of this information include where is the command defined, what are its keybindingings if any, and its documentation.
C-h w command-name
This will display the keybindings of the command in the minibuffer. If you’re interested only
in the keybindings you should prefer this option over
After you invoke some command using
M-x you’ll see a suggestion to use
its keybinding instead in the minibuffer.
That’s all for now, folks!
