If you unlock those three cells (Format Cells Protection tab, untick
Locked) then protect the worksheet (Tools Protection Protect Sheet),
then the tab button will cycle through those 3 cells.

A possible drawback with this is that the user will ONLY be able to enter
data in those 3 cells. On the other hand this could be an advantage :-)

I have a spreadsheet that I have three cells that I have limited the
number of characters/numbers that can be put in each cellt hrough
vailadation. Is there a way that when a person inputs the required
characters/numbers that the tab will go to the next cell? I have looked at
another question similiar to mine but that code does not work.
