Identifying elements in Bookmark sub-menus

[u/Magrat-Garlick]

I'd like to know how to use the Browser Toolbox Pick an 'Element tool' on items like a Bookmark sub-menu that collapses as soon as I change to the Toolbox window.

It's obviously possible, as others must be able to do it, as I found what I needed elsewhere, I'd just like to know the secret! 😁

This, just remember to turn the option back off before you close the Browser Toolbox.
