Key Mapping with xev and xmodmap under Linux
xmodmap met on Linux the same purpose as AutoHotkey under Windows: It maps certain mechanical keys on the virtual Numpad-digits:
- xev and xmodmap are pre-installed on Ubuntu already by default.
- You start xev with the command "xev" in the Terminal. It is an issue of during the term of entered keyboard Events appears. You tap the digits 0-9, the corresponding Keycodes to read. Read also the name of the behavior of the pressed button (the expression before the round bracket). By default, the Keycodes for the digit keys 10 to 19, and the Numpad-name KP_1 up KP_0 are.
- Now enter the commands for the Mapping in the Terminal: xmodmap -e "keycode 10 = KP_1 and so on for the nine digits. Replace the numbers and behavior-name by the xev values that are read.
