Sorry for not replying previously, for some reason I didn't see those
mails at all! I guess it's not so important now, but I'm using dual
function keys (which is a pretty awesome program) to virtually map
higher FN-keys, like F16, to the Alt-keys when they are tapped, then
configure Emacs to apply the Meta-modifier when it receives an F16
signal, which it calls XF86Launch6. This way, I don't have to
strain my hand holding Alt to apply Meta and can use the keys to access
another keyboard layer when they are held. Btw, with the same program
one can apply Ctrl when Space is held, greatly reducing hand strain.
