How do I make an FKEY?
I just picked up the FKEY manager (sorry, can't remember the author!), and
I may have a go at rolling my own...
   My LSC manual says that an FKEY is just a parameterless function, so
I presumably write

	pascal main()
	{
	   RememberA0(); SetUpA4();	/* Access my globals... */
	   ...
	   RestoreA4();
	}

and then build a code resource of type 'FKEY', and that's it. But:
(i)  What does an FKEY return? Is the value important?
(ii) does it really matter how much I do in the FKEY? It doesn't want to be
     anything too time-consuming, I suppose, but it can presumably call up
     dialogues and so on (if it assumes the managers are initialised...)
