If your cells are in a left to right and top to bottom order, see Debra's
answer.
If in a random order.................
You can use a named range to "jump" through in any order you design.
Select SECOND cell then CTRL + click on each succeeding cell in sequence, ending
up with the cell you want to start at.
Insert>Name Define........give your range a name and OK.
In namebox select the name and the cells will be highlighted in the order you
want.
Just type and hit ENTER key to go to next cell.
Note: there are limitations on the number of cells in a range.
See Bob Phillips' site for more help on this.
