could you please make a config file for the key binds, at least some options for alt, shift keys, because for some reason the Alt key is not being captured on my Ubuntu (i check the debug log and nothing pops up when i press Alt+R or Alt+Z). I tried remove all key shortcuts in the system that use Alt, but it still not work. Finally, I edit the source file and recompile the key binds with Shift (Shift+R, ....f +Z), then every thing works.
