I am editing with sublime text using a USB keyboard attached to my laptop. The keyboard has a numeric keypad which I would like to map to commands but sublime text only sees keypad_divide, keypad_multiply and keypad_minus. All other keys come up as if they were normal keys, e.g. home, left, pageup etc. I found this by setting sublime.log_input(True) in the console. I am using Centos7 and a UK keyboard. Any idea what could be wrong?
