Keyboard navigation for floating menus

For fun I created a "poor man's" keyboard navigation for the floating menus. :joy:

Assumed the menu is built vertically.

  1. A shortcut opens the menu and moves the mouse to the first button.

  2. "k" moves the mouse down one button. "j" moves the mouse one button up. If you need it, activate key repeat.

  3. Enter (or Space), triggers the macro of the highlighted button and closes the menu.

This just needs a CAG to set the actions of "k", "j" and Enter when the floating menu is open.
