Hi,

I recently acquired a workbook from another plant. The author is gone
so that source of information is gone. Here is the question: On a
column, if I select a cell in this column, a gray button with a down
pointing black arrow (dropdown?) appears to the right of the cell. If
I click the button, I get a choice block with an R in it. Then if I
click the R, an R appears in the cell. this was done to insure that
the proper letter and case was placed in the cell so a macro would
have the proper reference. I would like to learn how to add an remove
these buttons. Any ideas?

Secondly, I will continue this technique, however, it would make more
sense to provide an option button with one state adding an R to the
cell and the other leaving the cell blank. Any ideas?

Thanks in advance for helping my understanding!
