In GNOME bug 310842 the suggestion is raised that there should be an option to require all keybindings to be prefixed with a particular keystroke, to minimise the number of keystrokes which can’t be used by applications– there would be only one keystroke, the prefix, that was globally grabbed. Such a system would be reminiscent of ctrl-A in GNU Screen or ctrl-T in ratpoison. The default would be to keep things the way they are, of course.
It’s certainly doable, but would this be of use to anyone in the real world? Do any of you fancy justifying this idea?
