If I'm using Option as the Meta key, I want to suppress OS X GTK's default behaviour of treating it as an AltGr-oid which changes the keyval and Unicode translation of alphabetic keys. So on OS X I enable a somewhat bodgy workaround which retranslates from the hardware keycode as if the Option modifier had not been active at the time, and use that as the character to prefix Esc to. This is a bit nasty because I have to hardwire group = 0 in the call to gdk_keymap_translate_keyboard_state(), whereas in principle what I wanted was group = (whatever would have resulted from everything else in the key event other than MOD1). However, in practice, they seem to be the same, so this will do for the moment.
