Autohotkey macro: trying to remap left-alt to left-win; left-win to left-win with a toggle

I am trying to remap Left Alt to Left Win and Left Win to Left Alt in AutoHotKey.

But I also want to have Shift + F11 to toggle these two remaps.

I know I can do:

LAlt::LWin  
LWin::LAlt

but what I can't figure out is the toggle. The following version fails:

Shift & F11::
Hotkey, LAlt, Toggle
Hotkey, LWin, Toggle
return

When I press Shift and F11, it will say:

---------------------------

---------------------------
Error:  Nonexistent hotkey.  The current thread will exit.

OK

I've been scratching my head for hours.. Any input will be greatly appreciated!

I'm sure it is more verbose than necessary, but I just tried this script and it does something like what you're after. It might send you in the right direction, if nothing else.

IsRemapEnabled := false
