I don't get what you mean.  Please give example commands.

There is no deep, thought-out concept behind the rebinding code.
It seems to allow the things that are needed.

I'm don't think unbinding a key is ever necessary before binding
it to something else -- the binding code does this automatically.

Maybe your example works because no menu can contain both an Exit
and a Cancel -- when this does seem to be the case, the "Cancel"
is just an alias for Exit, added for convenience.

Adding ^K (and then also ^U) to the help of every prompt would
clutter the help lines.  The user wants to know what keystrokes
actually affect the Search, or the Read or the Write, not how to
edit what is typed at the prompt.  ^A and ^E, ^Left and ^Right,
and so on, are not explained either.
