How can i globally map <C-m> to work as <Return>? It is default in rxvt-unicode and vimperator, but i want it to work this way with any X application. I tried xbindkey with 'xdotool key Return', but it is too slow - about 1 sec delay, useless. Maybe it should be solved via WM (xmonad), but anyway i don't know how. Any solution?
