I'd put two little buttons from the Forms toolbar in adjacent cells and click on
them.

Assign each this macro:

Option Explicit
Sub testme01()

Dim myBtn As Button
Dim myCell As Range
With ActiveSheet
Set myCell = .Range("b1")
Set myBtn = .Buttons(Application.Caller)

If myBtn.TopLeftCell.Row = 1 Then
myCell.Value = myCell.Value & "C"
Else
myCell.Value = myCell.Value & "D"
End If
End With

End Sub


If you're new to macros, you may want to read David McRitchie's intro at:

I have a spread sheet that has descriptions and a letter
or number next to them. Example:

A1 B1
cat C
dog D

I want to be able to click on cat and populate cell C1
with the letter C and I want to be able to click on dog
and populate cell C1 with the letter D consectivly, so if
I clicked on cat then dog cell C1 would contain "CD", if i
clicked on dog then cat cell C1 would contain "DC"....how
can I do this in excell with a link or is there a better
way to make it work?
