I think the xlib function XQueryPointer (called queryPointer in the
haskell X11 binding) tells you which window is under the pointer. You
could try 'man XQueryPointer'.
Once you have that specific Window, you just have to:
focusWindowUnderPointer :: X ()
focusWindowUnderPointer = do
w <- queryPointer ...
windows (XMonad.StackSet.focusWindow w)
Then in your keybinding you'll just have something like:
In some cases it's possible to combine calls to `windows'. For example:
windows ( W.focusMaster . W.view "2" )
is a better way to do get the same result as:
windows (W.view "2")
With `focusWindowUnderPointer' that transformation is probably
possible too, but then you can't use queryPointer since the windows
aren't arranged when there's a chance to call queryPointer.
