Trap a key pressed in a dialog procedure

[ssimop]

To solve the latter, I followed this technique :

I issued a

case EN_SETFOCUS<<16|4

for each one of the fields involved in this inquiry, and I consequently stored the relevant number (4 in the case of this example) in a memory variable. Actually, this variable holds the field in which the Accelerator key was keyed. Any advice about other more efficient solutions is mostly welcome.
