Togglelink?

[looneytunes]

I have a form which is opened from the DoubleClick event of another form. when I view the code for this form, it has the following pieces of code:

Private Sub ToggleLink_Click()

Private Sub FilterChildForm()

Private Sub OpenChildForm()

Private Function ChildFormIsOpen()

Private Sub CloseChildForm()

i would be greatful if some1 could let me know what these stand for as i cannot find any reference to any of them anywhere in the dbase.
thanks
