Examples (7) from the manual page, untested
% xmodmap -e "pointer = 3 2 1"
Many pointers are designed such that the first button is pressed using the index finger of the right hand.% xmodmap -e "keysym Multi_key = Multi_key Meta_L"
Many applications support the notion of Meta keys (similar to Control keys except that Meta is held down instead of Control).% xmodmap -e "keysym Alt_L = Meta_L Alt_L"
Similarly, some keyboards have an Alt key but no Meta key.% xmodmap -e "keysym BackSpace = Delete"
One of the more simple, yet convenient, uses of xmodmap is to set the keyboard's "rubout" key to generate an alternate keysym.!
Some keyboards do not automatically generate less than and greater than characters when the comma and period keys are shifted.!
One of the more irritating differences between keyboards is the location of the Control and CapsLock keys.!
The keycode command is useful for assigning the same keysym to multiple keycodes.
