-- $usage
-- WindowPrompt brings windows to you and you to windows.
-- That is to say, it pops up a prompt with window names, in case you forgot
-- where you left your XChat.
--
-- You can use this module with the following in your @~\/.xmonad\/xmonad.hs@:
--
-- > import XMonad.Prompt
-- > import XMonad.Prompt.Window
--
-- and in the keys definition:
--
-- > , ((modMask x .|. shiftMask, xK_g ), windowPromptGoto defaultXPConfig)
-- > , ((modMask x .|. shiftMask, xK_b ), windowPromptBring defaultXPConfig)
--
-- The autoComplete option is a handy complement here:
--
-- > , ((modMask x .|. shiftMask, xK_g ), windowPromptGoto
-- > defaultXPConfig { autoComplete = Just 500000 } )
--
-- The \'500000\' is the number of microseconds to pause before sending you to
-- your new window. This is useful so that you don't accidentally send some
-- keystrokes to the selected client.
--
-- For detailed instruction on editing the key binding see
-- "XMonad.Doc.Extending#Editing_key_bindings".
