If using the data validation drop down you can do this. Sort your list to
have all the entries that begin with a at the top and the b's next all the
way to z.

At the beginning of each letter change in the list enter a single a at the
beginning of the a's, same with a b at the beginning of the b's etc. on to
z.

To go to the beginning of the t's for example, just type t in the drop down
cell and DON'T hit enter. Click on the drop down arrow and the t list will
appear. (You can hit enter after typing the letter but then you have to
reselect the drop down cell, just saves a step)

DATA VALIDATION - LIST - SOURCE; the entries on my "source" name is so
long
that I would like it to automatically go to the first selection when I
type
the first letter of what I'm looking for. Is this at all possible?
