Unfortunately, you can't - you need an object reference to use a method. You don't know what the "this" or "thisform" or "thisformset" relative reference will necessarily be at any given moment from the context of a menu or toolbar, and so blind reference to a method or the method of an object higher in the reference nest is not appropriate. If you need to have the ability to reference an objuect, you need to have a way of pointing to that object in a consistent fashion within your code. Code isn't good at guessing in what context something is meant, and we don't have a DWIM or DWIW (Do What I Mean/Do What I Want) construct available.
