I'm completely lost. Start from the beginning and explain to me what you're trying to do in concept.

As I said I have love/hate relationship with Global Modules.

The idea was like Lorenzo's where I don't want the user to press P or Ctrl P to print but rather use a button, either for  a list of reports and code within would let me know that they were printed afterwards.  But I didn't want to enter those 5 lines of code with each report.  One line would be enough

And as Dumb luck happens (again), I solved my issue, only after dropping it on this door mat.  The Global Module Public Sub is named HandleKeyDown and on the Report all I typed in the On KeyDown on the report was HandleKeyDown, instead of Call HandleKeyDown.

So I apologize to Lord Ricard King of Access for spending time reading my post.

Spelling, spelling, spelling
This is what Lord Richard King of access always tell us his faithful subjects.

Except the issue wasn't spelling it was forgetting to put the word Call

Here is the Global part

Public Sub HandleKeyDown(KeyCode As Integer, Shift As Integer)
    ' This subroutine will be called when the P key is pressed down
    
    If KeyCode = 80 And Shift = 2 Then
        MsgBox "Ctrl - P was pressed, please use Print Button", vbInformation, _
        "Warning"
        KeyCode = 0
    End If
    
End Sub

On the report

Private Sub Report_KeyDown(KeyCode As Integer, Shift As Integer)

    Call HandleKeyDown([KeyCode], [Shift])
    
End Sub

I missed the word Call in that line, which was really stupid because I did a Global earlier and remembered to Call.  So many things to remember and one more thing to forget.
