[xmonad] switch workspace on all monitors at once

Hi, I'm using three monitors and each monitor has 10 workspaces. This is the code I'm using to switch workspaces: [code] myWorkspaces = withScreens 3 ["1","2","3","4","5","6","7","8","9"] ... [((m .|. modm, k), windows $ onCurrentScreen f i) | (i, k) <- zip (workspaces' conf) [xK_1 .. xK_9] , (f, m) <- [(W.greedyView, 0), (W.shift, shiftMask)]] [/code] I wanted to modify it to add a keybind to switch the workspace on all three monitors at once. For example, control + modm + 2 would switch all monitors to workspace 2. But I'm afraid I don't understand whats going on in that code. Could someone give me a hand? Kristopher
