Oh, I just picked it because control-@ is the nul character, and your
commands would be nullified. I realize that's pretty weak, but we're
talking about finding a punctuation mark to represent the concept of
commands-are-currently-being-skipped, and it doesn't seem particularly
worse than ^ to represent single-line mode. If somebody's got a
better idea, fine, but there aren't that many unused punctuation marks
to choose from, and I think it's better to use a punctuation mark
rather than, say, a letter, like 's' for skip. Otherwise you might
have the prompt change from:
banana=>
to
bananas>
Which I think is less obvious than
banana@>
