I developed a VBA piece of code which I call up from a button but I would like to enhance it a bit so that when I place the cursor on the button the tooltip will say "change to 100% size" and then when I'm at 100% I would like the tooltip to say "change to 10% size" Here's the code I use at present. Public Sub CrosshairToggle() Dim PrefsDisplay as AcadPreferencesDisplay Set PrefsDisplay = ThisDrawing.Application.Preferences.Display If PrefsDisplay.CursorSize = 10 then PrefsDisplay.CursorSize = 100 Else: PrefsDisplay.CursorSize = 10 End If End Sub Can anyone show me how to change the tooltip TIA DonB
