John, I that you misunderstood Jeffs idea, he wasn't suggesting to do a 
pushkey "B" in @keyB.  He is suggesting to trap the B key in @entsel 
processing, of course putting @keyB pushkey "B" would cause an eternal 
loop, but using a waitkey in @entsel just might work....the only problem 
I can forsee is that I'll have to catch every single key for which we 
have processing (which is a lot), but if I put the waitkey into a 
variable, zz, then if zz is not equal to 'B' I could pushkey zz....I 
plan to test this out and I'll let you know what I find, the theory 
seems sound though.

Thanks,
