menus: Place ListMenu as a keyboard-accesisble menu

Remove the `DataMenu`.

Replace `PrintMenu` with `ListMenu` as keyboard-accessible menu
(we can tuck the rarely used `PrintMenu` under `I/O`)

Add list product, sum, etc to `ListMenu`

Modify `ProgramMenu` to add special program entry characters.
