Ok, space is out.

*thinks*

Ok, "b for back" is out because "b" on the main menu is boot (even if not highlighted -- see menu.rc keycode[1] and corresponding ascii(7), decimal 'b' is 98).

Ok, space, any F# keys, any arrow keys, and backspace are also out.

Hmmm…

I'm looking at my keyboard and nothing really sticks out.

'M' perhaps for "Back to [M]ain Menu"
