I'm having a hard time figuring out exactly what you're asking in the above 
message.  However, I am guessing that you are asking why, after executing 
the above "@wukaa" line, the "@wlfaa" event is triggered.  If that's your 
question, the answer is because the "screen ,aa" statement causes the cursor 
to leave the current field (in this case, aa) in order to move the cursor to 
field aa.

Since @wuk doesn't leave the field, just "end" the event, and the cursor 
will remain in the current field.
