-- Copyright : (c) David Glasser 2007

-- Maintainer : glasser@mit.edu
-- Stability : stable
-- Portability : portable
--
-- Allows you to run internal xmonad commands (X () actions) using
-- a dmenu menu in addition to key bindings. Requires dmenu and
-- the Dmenu XMonadContrib module.

-- $usage
--
-- To use, modify your Config.hs to:
--
-- > import XMonadContrib.Commands
--
-- and add a keybinding to the runCommand action:
--
-- > , ((modMask .|. controlMask, xK_y), runCommand)
--
-- and define the list commands:
--
-- > commands = defaultCommands
--
-- Finally, add the following lines to Config.hs-boot:
--
-- > import XMonad (X)
-- > workspaces :: Int
-- > commands :: [(String, X ())]
--
-- A popup menu of internal xmonad commands will appear. You can
-- change the commands by changing the contents of the list
-- 'commands'. (If you like it enough, you may even want to get rid
-- of many of your other key bindings!)
