Sure. Lets say the validation cells are A1, B2, C3, D4, E5, F6 and you want
to move through them in just that order.
Select B2 and hold down the CTRL key and with the CTRL key held down select
the other cells, C3 then D4 then E5 then F6 and last A1. Now release the
CTRL key and while all the cells are still selected, click in the Name Box,
which is just above the A column. It will have A1 in it. When you click in
the box it will highlight A1 and move it to the left. Just type in a name,
i.e. MyValCells. Hit Enter.
To use, notice the small down arrow just to the right of the Name Box.
Click it and the Name Box will display all named ranges on the sheet. You
should see MyValCells, just click on it and the range on the sheet will be
highlighted, with A1 as the current selection. Make your data validation
choice for A1 and use either Enter or Tab to move to the next cell. Do the
same with each cell. When done click elsewhere on the sheet to remove the
highlighting.
