SET KEY for ENTER

Hi,

I have a map (which basically has information to be read from, that it is a reference map) and this is a third level map. A PF3 on this takes to the previous map. ENTER key is also doing the same (since by default ENTER key should function like that).
Is there a way to disable this ENTER key on the map - that is, on depressing the ENTER KEY , no action should happen on the map.
Is there a way that has been tested and verified.

Regards,
Ajith

Follwoing Code in a Key-Rule on the map will work as you want:
IF *PF-KEY = ´ENTR´
REINPUT FULL ´ ´
END-IF
