I'd like to be able to send middle mouse clicks from a keyboard key, for example, the right control key (keycode 105 on my keyboard).

I can remap it using xmodmap like so:

xmodmap -e "keycode 105 = Pointer_Button2"

But it only seems to work if I have mousekeys enabled, by running one of the following:

  • Shift-Numlock
  • dconf write /org/gnome/desktop/a11y/keyboard/mousekeys-enable true
  • xkbset m && xkbset exp =m

This remaps the numeric keypad to control the cursor.

Is there some way I can get X to accept mouse events from keyboard keys without converting the numpad to a cursor control?

Yes it can :) You have two choise. A smart but dirty way is to use xmodmap -e to remap all keypad to corrensponding value on keyboard. Like KP9 to 9 (the proccess is the same as you do for mouse button)

The second way is to go /usr/share/X11/xkb/compat/mousekeys, read the file carefully and remove or comment those who are in relation with keypad. (you can comment is c++ way using //)

After edit, reboot the X or your computer and enabling xkb mouse controlbit by xkbset m won't affect keypad anymore.

PS: by the way I want to remap a key to mouse button 9 but Pointer_Button9 is not defined :( any comment?
