-- | 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.

-- | Width of the window border in pixels.
 
--

-- | 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
 
--
 
-- Fields are: top, bottom, left, right.

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.
