Use xev
to get keycode and name (note that these key codes differ from when using showkey -k
when not in X).
Forward key…
KeyPress event, serial 27, synthetic NO, window 0x3a00001,
root 0x3e, subw 0x0, time 3026042600, (107,-95), root:(365,188),
state 0x10, keycode 233 (keysym 0x0, NoSymbol), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
KeyRelease event, serial 27, synthetic NO, window 0x3a00001,
root 0x3e, subw 0x0, time 3026042768, (107,-95), root:(365,188),
state 0x10, keycode 233 (keysym 0x0, NoSymbol), same_screen YES,
XLookupString gives 0 bytes:
XFilterEvent returns: False
Back key…
KeyPress event, serial 27, synthetic NO, window 0x3a00001,
root 0x3e, subw 0x0, time 3026041000, (107,-95), root:(365,188),
state 0x10, keycode 234 (keysym 0x0, NoSymbol), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
KeyRelease event, serial 27, synthetic NO, window 0x3a00001,
root 0x3e, subw 0x0, time 3026041272, (107,-95), root:(365,188),
state 0x10, keycode 234 (keysym 0x0, NoSymbol), same_screen YES,
XLookupString gives 0 bytes:
XFilterEvent returns: False
(Btw, use xmodmap -pke
to view key map.)
Remap keys…
xmodmap -e "keycode 233 = Right"
xmodmap -e "keycode 234 = Left"
Add the following to /etc/X11/xinit/xprofile (for system wide) or ~/.xprofile (for user) to make permanent:
xmodmap -e "keycode 233 = Right" &
xmodmap -e "keycode 234 = Left" &
Don’t forget the ampersands.
The Forward key will now send Right and the Back key will send Left.
