Some users tell me that they don't have an F12 key on their keyboard,
Clint. I've never encountered such a keyboard, personally, but that's
what they tell me...

The first-time-you-press-ctrl-a thing is meant to be pretty permanent,
I'm afraid, Clint. You'll be asked the question in byobu tmux or
screen. You have the option of choosing to have ctrl-a behave in GNU
Screen mode, or behave in GNU Emacs mode (and F12 becomes your
escape).

Unfortunately, I don't think that the status line refreshes fast
enough for this to be useful. It refreshes about once-per-second,
which is eons in the scope of keypresses. I'll give that some more
thought, though, as I do like the idea of a visual queue that you're
in screen or tmux escape mode...
