I have downloaded this editor from Codeguru by Hannes DuPreez

https://www.codeguru.com/visual-basi...-visual-basic/

With a few minor changes it appears to work well.
However there is one thing I cannot work out:

There is a Private Sub MruItem_Click(,) which implies there is a menu item or control for the Click event, but I cannot see what it might be.

Can anyone assist?
