xmonad.hs
-- xmonad example config file for xmonad-0.9
--
-- A template showing all available configuration hooks,
-- and how to override the defaults in your own xmonad.hs conf file.
--
-- Normally, you'd only override those defaults you care about.
--
-- NOTE: Those updating from earlier xmonad versions, who use
-- EwmhDesktops, safeSpawn, WindowGo, or the simple-status-bar
-- setup functions (dzen, xmobar) probably need to change
-- xmonad.hs, please see the notes below, or the following
-- link for more details:

-- 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.
--
myModMask = mod1Mask
-- NOTE: from 0.9.1 on numlock mask is set automatically. The numlockMask
-- setting should be removed from configs.
--
-- You can safely remove this even on earlier xmonad versions unless you
-- need to set it to something other than the default mod2Mask, (e.g. OSX).
--
-- 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.
