Hello.

Few months ago I became a incredibly happy user of the tiling window manager XMonad. Though I know only the very basics of Haskell, I managed to create a desirable configuration with the help of this post and this perfectly documented config for Ubuntu.

Yet I have a question on switching workspace layouts. I'd like the Mod + Shift + Space shortcut to switch to previous workspace instead of the first (default) one. In default config I found only:

     -- Rotate through the available layout algorithms
    , ((modm,               xK_space ), sendMessage NextLayout)
 
    --  Reset the layouts on the current workspace to default
    , ((modm .|. shiftMask, xK_space ), setLayout $ XMonad.layoutHook conf)

Also looking through XMonad.Layout I could find only NextLayout and FirstLayout messages. No PreviousLayout. Is there any straight forward way to implement that?

Thank you.

Sincerely, Ruslan Kiianchuk.
