Xkb adds its own mask and prevent Submap keybindings from normal functioning when alternate layout is used. This patch cleans these masks.

First, import this module into your @~\/.xmonad\/xmonad.hs@:
|
|
|
|
> import XMonad.Actions.Submap
|
|
|
|
Allows you to create a sub-mapping of keys. Example:
|
|
|
|
> , ((modMask x, xK_a), submap . M.fromList $
|
|
> [ ((0, xK_n), spawn "mpc next")
|
|
> , ((0, xK_p), spawn "mpc prev")
|
|
> , ((0, xK_z), spawn "mpc random")
|
|
> , ((0, xK_space), spawn "mpc toggle")
|
|
> ])
|
|
|
|
So, for example, to run 'spawn \"mpc next\"', you would hit mod-a (to
|
|
trigger the submapping) and then 'n' to run that action. (0 means \"no
|
|
modifier\"). You are, of course, free to use any combination of
|
|
modifiers in the submapping. However, anyModifier will not work,
|
|
because that is a special value passed to XGrabKey() and not an actual
|
|
modifier.
|
