First unlock the cells where the user will be entering their response
(FormatCellsProtectionLocked)
Then protect the sheet. When you press tab, each of the unlocked cells will
be accessed in turn. You could put an instruction to the user to that effect.

I'm creating a questionnaire that will allow the user to input data in

appreciated
