Hi Tech Expert, I got similar problem where I don't want C1 TO C4 keys on TDE to scroll screen when in RUN mode unless asked for in the program. You suggested to keep Logo in operator mode to disable C1 to C4 keys unless called for in program. I had a look at Logo or TDE and couldn't figure out how to do that. Pls advise.

No, it is not possible to deactivate the cursor keys (C1 to C4) on the base module or on the TDE in order to prevent scrolling between activated message texts in RUN mode.
Switching to the operator mode only limits the operability. For example, it limits the usability of the menu, in which certain menu items can no longer be selected.
