From my experience, you don't. You just need to re-select.
If you are doing this to record a Macro, just complete it and go back and
edit the selection once you finish. If that's not an option, Good luck. Never
been in a sitation where a selection couldn't be re-done.

Starting in cell A2 I have selected a range that continues to cell A16.
Then, I have realized I meant to include cell A1 as well. Since I started in
A2 if I attempt to extend the range I will go to A17. Without deselecting
the already selected range of A2:A16 how do I change the position of the
cursor to include A1. Thank you.
