How can I capture the event in Excel when a user clicks on a cell. I want to be able to use this event to trigger some code to count how many times the user clicks on several different cells in a column.
Check out the Worksheet_SelectionChange event. In that event you could use Intersect() with named ranges to figure out if a specific range were clicked.
Here's some code that might help you get started.
Private Sub Worksheet_SelectionChange(ByVal Target As Excel.Range)
If Not Intersect(Target, Range("SomeNamedRange")) Is Nothing Then
'Your counting code
End If
End Sub
