MS-Word VBA How to Identify click object

Question

I have a label object called Lb1. and a sub:

Private Sub Lb1_Click()
call function(Lb1)

End Sub

But I want to use this function in all other click objects, with a variable as an argument, a variable that should point to the clicked object itself. I dont want to change the argument manually for every click object. Is there a method in VBA, to identify the clicked object and return the object?

Thank you very much!
