I come from a 'CAD"-centric environment where a lot of our tools and macros are setup to pick a tool and then pick where to use it. To have an option to work that way in other software would seem very natural to us.
I was hoping for an example that I could adapt where I could select the name of a bookmark from a list - not necessarily of existing bookmarks, in fact, in most cases it would be a list of bookmarks to be created - and then prompt the user to click in a cell in a table that indicates where the bookmark is to be placed.
