You can use this module with the following in your ~/.xmonad/xmonad.hs:

 import XMonad.Actions.Warp

then add appropriate keybindings to warp the pointer; for example:

 , ((modMask x,   xK_z     ), warpToWindow (1%2) (1%2)) -- @@ Move pointer to currently focused window

-- mod-ctrl-{w,e,r} @@ Move mouse pointer to screen 1, 2, or 3

   [((modMask x .|. controlMask, key), warpToScreen sc (1%2) (1%2))
       | (key, sc) <- zip [xK_w, xK_e, xK_r] [0..]]

Note that warping to a particular screen may change the focus.

Move the mouse cursor to a corner of the screen. Useful for uncluttering things.

Internally, this uses numerical parameters. We parametrize on the Corner type so the user need not see the violence inherent in the system.

warpToScreen and warpToWindow can be used in a variety of ways. Suppose you wanted to emulate Ratpoison's 'banish' command, which moves the mouse pointer to a corner? warpToWindow can do that!
