+-- | The default number of workspaces (virtual screens) and their names.
+-- By default we use numeric strings, but any string may be used as a
+-- workspace name. The number of workspaces is determined by the length
+-- of this list.
+--
+-- A tagging example:
+--
+-- > workspaces = ["web", "irc", "code" ] ++ map show [4..9]
+--
+workspaces :: [WorkspaceId]
+workspaces = map show [1 .. 9 :: Int]
+
+-- | modMask lets you specify which modkey you want to use. The default
+-- is mod1Mask ("left alt").  You may also consider using mod3Mask
+-- ("right alt"), which does not conflict with emacs keybindings. The
+-- "windows key" is usually mod4Mask.
+--
+modMask :: KeyMask
+modMask = mod1Mask
+
+-- | The mask for the numlock key. Numlock status is "masked" from the
+-- current modifier status, so the keybindings will work with numlock on or
+-- off. You may need to change this on some systems.
+--
+-- You can find the numlock modifier by running "xmodmap" and looking for a
+-- modifier with Num_Lock bound to it:
+--
+-- > $ xmodmap | grep Num
+-- > mod2        Num_Lock (0x4d)
+--
+-- Set numlockMask = 0 if you don't have a numlock key, or want to treat
+-- numlock status separately.

+
+-- | Default offset of drawable screen boundaries from each physical
+-- screen. Anything non-zero here will leave a gap of that many pixels
+-- on the given edge, on the that screen. A useful gap at top of screen
+-- for a menu bar (e.g. 15)
+--
+-- An example, to set a top gap on monitor 1, and a gap on the bottom of
+-- monitor 2, you'd use a list of geometries like so:
+--
+-- > defaultGaps = [(18,0,0,0),(0,18,0,0)] -- 2 gaps on 2 monitors

+-- Window rules
+
+-- | Execute arbitrary actions and WindowSet manipulations when managing
+-- a new window. You can use this to, for example, always float a

+--
+-- To find the property name associated with a program, use
+--  xprop | grep WM_CLASS
+-- and click on the client you're interested in.

+
+-- Always float various programs:
+manageHook w _ _ c | c `elem` floats = fmap (W.float w . snd) (floatLocation w)
+ where floats = ["MPlayer", "Gimp"]
+
+-- Desktop panels and dock apps should be ignored by xmonad:
+manageHook w _ n _ | n `elem` ignore = reveal w >> return (W.delete w)
+ where ignore = ["gnome-panel", "desktop_window", "kicker", "kdesktop"]
+
+-- Automatically send Firefox windows to the "web" workspace:
+-- If a workspace named "web" doesn't exist, the window will appear on the
+-- current workspace.

+--
