Thank you Michael.
That makes sense.

Anyway, I'm using MoI4beta 99% of the time so I'll keep the MoI3 .ini the same as MoI4beta's.

Yes, your explanation is correct.
With MoI4beta closed, I opened MoI3, and changed the CTRL+Alt+N shortcut key by adding ZONK before the final semicolon.
Closed MoI3. Opened MoI4beta. The shortcut key alerted finding "ZONK,' and did not load nodeeditor.
Removed ZONK, closed and reopened MoI4beta, and the hotkey worked to load nodeeditor Light scheme.
The Light scheme is more printer toner friendly...
