Hm, that's annoying, sorry I didn't catch it.
One of my very favorite things about OSX is that since the standard meta key
is cmd instead of ctrl, all regular GUI bindings (entirely cmd-based) and
all emacs-style bindings (ctrl-based) have no degeneracy, so you don't have
to choose between having ctrl-a be home or select-all, or this cmd/ctrl-P
behavior, and basic emacs navigation works in *all* GUI apps by default.

Yes, we should do a platform check, since it would be completely hideous to
be the only Mac app in the world that doesn't use cmd-P for print.
Is it just Linux, or will there also be a conflict in Windows?
Specifically: is OSX the only one without a problem, or is Linux the only
one with a problem?
Is there a similar conflict on ctrl-S?
