Hi.

Is it possible to insert the letter "x" into a cell automatically whenever any cell in a range is clicked on with the mouse?

If so, can someone be kind enough to show me how, please?

Thanks.

Is it also possible to do the same task by highlighting more than one cell in the range?

Thanks.

Excel doesn't provide a propper Click event. The closest is to use the worksheet selection_change event. Unfortunately, this event also fires when selecting cells with the keyboard navigation keys hence it is of no use. Trapping mouse clicks in excel is not easy. Setting a Windows mouse hook, subclassing the excel application or using a Windows timer would work but it would make excel unstable and potentially crash the entire application.

I use a hacky alternative which works for trapping mouse clicks on cell(s) exclusively and ignores keyboard selections/navigation. It is not super fast but it is acceptable and most importantly, it won't make excel unstable and won't crash the application should an unhadled error occur..

In your case, you will just have to edit the event handler code that is located in the ThisWorkbook module as a minimum as follows:
VBA Code: 
Private Sub Workbook__SheetClick(ByVal Sh As Worksheet, ByVal Target As Range, ByRef DisableDBlClick As Boolean)
    Target.Value = "X"
End Sub

Notice the Sh, Target and DisableDBlClick arguments. You can use/set them to restrict/specify the span of action to which the code will be applied, just like we do with standard native events.

Maybe selecting with the keyboard might also suit the you? If so, you could try this much simpler Worksheet_SelectionChange code with a copy of your workbook (changing the relevant range as required).
Post back if you need instructions on how to implement it.

VBA Code: 
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
  Dim rSelected As Range
  
  Set rSelected = Intersect(Target, Range("B2:F20"))
  If Not rSelected Is Nothing Then rSelected.Value = "x"
End Sub

Thanks very much Peter. I'll have a play with both options and see what happens. I'll let you know also what happens.
