Configure XMonad Tall layout to expand all the way to the screen border

I use the XMonad Tall layout and can expand and shrink the master area with mod-l and mod-h.

Question: Is there a possibility to to expand the master area all the way to the border of the screen with one keystroke (instead of having to press mod-l serveral times?). Something like a full-screen key combination. Is there then even a reverse key combinations to get out of full-screen mode again. Does anyone know an example howto set this up? I think I could use the Full layout for this, however I want to avoid having to cycle though the layouts with mod-space. How can I bind a keycombination to select a specific layout? (i.e. mod-shift-l to cycle between Full and Tall layout only).

Solution

Found the answer:

To toggle between Full-Layout and a set of other layouts, in my case Tall and Tabbed, I did:

...
import XMonad.Layout.ToggleLayouts
...
myLayout =  avoidStruts (
    toggleLayouts Full (
                  Tall 1 (10/100) (2/3) |||
                  tabbed shrinkText tabConfig
                  )
    )
...

  -- Switch to Full layout.
  , ((modMask .|. shiftMask, xK_l),
      sendMessage (Toggle "Full") )

Then, by pressing mod-shift-l Fullscreen Layout is enabled and reverted the next time mod-shift-l is pressed. Snippet from https://gist.github.com/jianingy/5472640 , I dont have the slightest clue how Haskell works...
