You can set up a cell to call a macro when it is clicked, but there is a
problem. The macro will be called even if you run across the cell with the
arrow keys or ENTER key. That is why a double click is usually reccommended.
Try this worksheet event macro:
Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As
Set t = Target
Set a1 = Range("A1")
If Intersect(t, a1) Is Nothing Then Exit Sub
Cancel = True
Because it is worksheet code, it is very easy to install and automatic to use:
1. right-click the tab name near the bottom of the Excel window
2. select View Code - this brings up a VBE window
3. paste the stuff in and close the VBE window
If you have any concerns, first try it on a trial worksheet.
If you save the workbook, the macro will be saved with it.
To remove the macro:
1. bring up the VBE windows as above
2. clear the code out
3. close the VBE window
