Keybinding menu

[tylerdurden4285]

Hi, I appreciate you put the keybindings in the git README.md but could it be added to the actual menu of the tool? I see a help when I click H and it would be amazing if we could have Keybindings list when we click K

The alternative is having to come back to this git repo and scroll down to check them until I memorize them.

It's not a big problem of course, but it is a reasonable request.
