Switch keyboard keys
xev and press any key to find the key codes, the output is something like this:
state 0x10, keycode 78 (keysym 0xff14, Scroll_Lock), same_screen YES,
state 0x10, keycode 62 (keysym 0xffe2, Shift_R), same_screen YES,
state 0x11, keycode 11 (keysym 0x40, at), same_screen YES,
Switch keys by:
xmodmap -e "keycode 78 = at"
Save to prevent reset after booting:
xmodmap -pke|egrep -e '78'
That will print a line like:
keycode 78 = at NoSymbol at
Create file ~/.Xmodmap and copy to it.
