More specific question on @SK

[Richard Kreiss]

What you all are missing is that @sk only excepts special keys while @bk accepts key strokes other then special keys. 

Therefore, one could say
If: @sk = "BRKY" or @BK="x"
Then: clearb; goto nnn

As I see it, @sk only takes the 4 character value as defined in special keys while used in input processing with '@wlfxx.

I would expect that @sk would have the last special key that was pressed during data input commands.  That seems intuitive to me.  Logically, if a value goes into @bk it does not exclude the possibility that it also goes into @sk.
