-- You can use this module with the following in your
|
|
-- @~\/.xmonad\/xmonad.hs@:
|
|
--
|
|
-- > import XMonad.Layout.BoringWindows
|
|
--
|
|
-- Then edit your @layoutHook@ by adding the layout modifier:
|
|
--
|
|
-- > myLayout = boringWindows (Full ||| etc..)
|
|
-- > main = xmonad def { layoutHook = myLayout }
|
|
--
|
|
-- Then to your keybindings, add:
|
|
--
|
|
-- > , ((modm, xK_j), focusUp)
|
|
-- > , ((modm, xK_k), focusDown)
|
|
-- > , ((modm, xK_m), focusMaster)

An alternative to 'Full' is "XMonad.Layout.Simplest". Less windows are
|
|
ignored by 'focusUp' and 'focusDown'. This may be helpful when you want windows
|
|
to be uninteresting by some other layout modifier (ex.
|
|
"XMonad.Layout.Minimize")
