I was thinking I would like to banish the mouse at every input,
going beyond what it says in the info page:
To do this, I think I would want to have _every_ key that sends input
to the underlying program be in the "top" keymap; compare the
`self-insert-command' function from Emacs. Perhaps keypress should be
added to RP as a `self-insert-command' analogue (see email from Martin
circa April of this year).
(But for the immediate purposes of this question, is there a way to
perma-banish the mouse without running banish all the time? I am
already using "unclutter", but the mouse can still be annoying when it
drifts across the screen invisibly, causing mouse-over events to
happen in the windows below.)
