Exactly. Use this version of the FS functions:

  DestroyFunc FullScreenToggle
  AddToFunc FullScreenToggle
  + I ThisWindow (State 23) FullScreenOff
  + I TestRc (!Match) FullScreenOn

  DestroyFunc FullScreenOn
  AddToFunc FullScreenOn
  + I WindowStyle !Title, !Borders
  + I Raise
  + I UpdateStyles
  + I Maximize on 100 100
  + I State 23 on

  DestroyFunc FullScreenOff
  AddToFunc FullScreenOff
  + I WindowStyle Title, Borders
  + I Maximize off
  + I State 23 off

And

  + I Current (Maximized, !State 23) + "Unmaximize" Maximize false
  + I Current (!Maximized) + "Maximize..." Maximize -60p 100
  + I Current (State 23) + "Unfullscreen" UnFullScreen
  + I Current (!State 23) + "Fullscreen" FullScreen

But you need to upgrade to 2.5.12 to make it work. There is a bug
in 2.5.11 (it erases the state when WindowStyle is called).

I think so. TestRc should mainly be used with the break command,
not to code different types of behaviour into one functions. It's
too easy to get it all wrong.
