Provides methods for cycling through groups of windows across workspaces, ignoring windows that do not belong to this group. A group consists of all windows matching a user-provided boolean query.

Also provides a method for jumping back to the most recently used window in any given group, and predefined groups.

Import the module into your ~/.xmonad/xmonad.hs:

import XMonad.Actions.GroupNavigation

To support cycling forward and backward through all xterm windows, add something like this to your keybindings:

, ((modm              , xK_t), nextMatch Forward  (className =? "XTerm"))
, ((modm .|. shiftMask, xK_t), nextMatch Backward (className =? "XTerm"))

These key combinations do nothing if there is no xterm window open. If you rather want to open a new xterm window if there is no open xterm window, use nextMatchOrDo instead:

, ((modm              , xK_t), nextMatchOrDo Forward  (className =? "XTerm") (spawn "xterm"))
, ((modm .|. shiftMask, xK_t), nextMatchOrDo Backward (className =? "XTerm") (spawn "xterm"))

You can use nextMatchWithThis with an arbitrary query to cycle through all windows for which this query returns the same value as the current window. For example, to cycle through all windows in the same window class as the current window use:

, ((modm , xK_f), nextMatchWithThis Forward  className)
, ((modm , xK_b), nextMatchWithThis Backward className)

Finally, you can define keybindings to jump to the most recent window matching a certain Boolean query. To do this, you need to add historyHook to your logHook:

main = xmonad $ def { logHook = historyHook }

Then the following keybindings, for example, allow you to return to the most recent xterm or emacs window or to simply to the most recent window:

, ((modm .|. controlMask, xK_e),         nextMatch History (className =? "Emacs"))
, ((modm .|. controlMask, xK_t),         nextMatch History (className =? "XTerm"))
, ((modm                , xK_BackSpace), nextMatch History (return True))

Again, you can use nextMatchOrDo instead of nextMatch if you want to execute an action if no window matching the query exists.

Below are handy queries for use with nextMatch, nextMatchOrDo, and nextMatchWithThis.
