Hello, I'm a happy user of xmonad since about 1 year. But I don't know haskell language at all. (I know: I should learn, but… lack of time, and also happy OCaml programmer). My problem: I just installed a brand new computer. Then xmonad, and I use it with Gnome. My xmonad.hs is: import XMonad import XMonad.Config.Gnome main = xmonad gnomeConfig { modMask = mod4Mask } I now want to integrate some more key bindings, but I'm not able to put together all the informations gathered from the documentation. Here are the binding I'd like to add: -- import XMonad.Actions.CycleWS -- import qualified XMonad.StackSet as S ------------------------------------------------------------------------ -- Key bindings. Add, modify or remove key bindings here. -- -- myKeys conf = -- -- -- -- -- mod-[1..9], Switch to workspace N -- -- mod-shift-[1..9], Move client to workspace N -- -- -- [((modMask, k), windows $ S.greedyView i) -- | (i, k) <- zip (XMonad.workspaces conf) [xK_F1 .. xK_F9] -- -- , (f, m) <- [(W.greedyView, 0), (W.shift, shiftMask)] -- ] -- ++ -- [ ((modMask, xK_Left ), prevWS ) -- , ((modMask, xK_Right ), nextWS ) -- , ((modMask .|. shiftMask, xK_Left ), shiftToPrev ) -- , ((modMask .|. shiftMask, xK_Right ), shiftToNext )] First problem: the last 2 lines have a problem. Couldn't match expected type `XConfig l -> KeyMask' against inferred type `KeyMask' In the second argument of `(.|.)', namely `shiftMask' In the expression: modMask .|. shiftMask In the expression: (modMask .|. shiftMask, xK_Left) Second problem: how to integrate myKeys with Config.Gnome bindings ? Thanks in advance Matt
