You can try but no guarantees.
I've been using buttons > 5 since forever and have never had problems. Just check xev to tell what button has what number. (My X11/X.h goes only up to 5. Who cares.) For inspiration, a snippet from my xmonad.hs. My laptop's touchpad allows scrolling left/right as well as up/down. -- Mod + vertical scrolling = move focus, with Alt it moves windows. -- Mod + horizontal scrolling = resize the master pane, with Alt it changes number of windows in master. -- -- So is that cool or what? ;-) let leftclick = 1 middleclick = 2 rightclick = 3 wheelup = 4 wheeldown = 5 wheelleft = 6 wheelright = 7 in withMask modm -- Set the window to floating mode and move by dragging [ (leftclick , \w -> focus w >> mouseMoveWindow w) -- Raise the window to the top of the stack , (middleclick, \w -> focus w >> windows W.swapMaster) -- Set the window to floating mode and resize by dragging , (rightclick, \w -> focus w >> mouseResizeWindow w) , (wheelup , \_ -> windows W.focusUp) , (wheeldown , \_ -> windows W.focusDown) , (wheelleft , \_ -> sendMessage Shrink) , (wheelright, \_ -> sendMessage Expand) ++ withMask (modm .|. alt) [ (wheelup , \_ -> windows W.swapUp) , (wheeldown , \_ -> windows W.swapDown) , (wheelleft , \_ -> sendMessage $ IncMasterN 1) , (wheelright, \_ -> sendMessage $ IncMasterN (-1)) ] -- Not very important. Tiny function the above code relies on. withMask m = map (\(sym, action) -> ((m, sym), action)) Cheers, Hendrik -- "1 + 1 = 3, for large values of 1."
