Adding the PORT_CODEs to both lines should work for "emulated keyboard" mode, yes. The PORT_CHAR stuff is for the "natural keyboard" mode - I'm not sure if any change would be needed there. The right shift at least seems to already work in natural keyboard mode, I don't know what the control key is supposed to do in MC-1000 so I can't check.
