Import the module into your ~/.xmonad/xmonad.hs:
import XMonad.Actions.WindowGo
and define appropriate key bindings:
, ((modMask x .|. shiftMask, xK_g), raise (className =? "Firefox")) , ((modMask x .|. shiftMask, xK_b), runOrRaise "firefox" (className =? "Firefox"))
(Note that Firefox v3 and up have a class-name of "Firefox" and "Navigator"; lower versions use other classnames such as "Firefox-bin". Either choose the appropriate one, or cover your bases by using instead something like (className =? "Firefox" || className =? "Firefox-bin").)
For detailed instructions on editing your key bindings, see XMonad.Doc.Extending#Editing_key_bindings.
raiseMaybe queries all Windows based on a boolean provided by the user. Currently, there are three such useful booleans defined in XMonad.ManageHook: title, resource, className. Each one tests based pretty much as you would think. ManageHook also defines several operators, the most useful of which is (=?). So a useful test might be finding a Window whose class is Firefox. Firefox 3 declares the class "Firefox", so you'd want to pass in a boolean like (className =? "Firefox").
If the boolean returns True on one or more windows, then XMonad will quickly make visible the first result. If no Window meets the criteria, then the first argument comes into play.
The first argument is an arbitrary IO function which will be executed if the tests fail. This is what enables runOrRaise to use raiseMaybe: it simply runs the desired program if it isn't found. But you don't have to do that. Maybe you want to do nothing if the search fails (the definition of raise), or maybe you want to write to a log file, or call some prompt function, or something crazy like that. This hook gives you that flexibility. You can do some cute things with this hook. Suppose you want to do the same thing for Mutt which you just did for Firefox - but Mutt runs inside a terminal window? No problem: you search for a terminal window calling itself "mutt", and if there isn't you run a terminal with a command to run Mutt! Here's an example (borrowing runInTerm from XMonad.Utils.Run):
, ((modm, xK_m), raiseMaybe (runInTerm "-title mutt" "mutt") (title =? "mutt"))
