With XDG support so firmly ingrained now, it's about time we stop hard-coding the configuration path in the docs.

-- $usage
|
|
--
|
|
-- You can use this module with the following in your @xmonad.hs@:
|
|
--
|
|
-- > import XMonad.Actions.PerWindowKeys
|
|
--
|
|
-- > ,((0, xK_F2), bindFirst [(className =? "firefox", spawn "dmenu"), (isFloat, withFocused $ windows . W.sink)])
|
|
--
|
|
-- > ,((0, xK_F3), bindAll [(isDialog, kill), (pure True, doSomething)])
|
|
--
|
|
-- If you want an action that will always run, but also want to do something for
|
|
-- other queries, you can use @'bindAll' [(query1, action1), ..., (pure True,
|
|
-- alwaysDoThisAction)]@.
|
|
--
|
|
-- Similarly, if you want a default action to be run if all the others failed,
|
|
-- you can use @'bindFirst' [(query1, action1), ..., (pure True,
|
|
-- doThisIfTheOthersFail)]@.
