Toggle colour of a clicked-on cell

daba1955 

Excel does not really have an event for when a cell is clicked. It has an event that occurs when the selection changes. If you select a cell by clicking on it or using the keyboard to move to it, the event will occur. But if you click on the same cell again, no event occurs because the selection doesn't change.

It might be better to use a double-click.

Right-click the sheet tab.

Select 'View Code' from the context menu.

Copy the following code into the worksheet module.

Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
    Const TheCells = "A2:A5,C2:C5"
    If Not Intersect(Range(TheCells), Target) Is Nothing Then
        If Target.Interior.Color = vbRed Then
            Target.Interior.Color = vbGreen
        Else
            Target.Interior.Color = vbRed
        End If
        Cancel = True
    End If
End Sub

Change the value of the constant TheCells to the list of cells you want to toggle.

Switch back to Excel.

Save the workbook as a macro-enabled workbook.

Make sure that you allow macros when you open it.
