File type context menu separator

I have setup a very useful context menu to move screencaptured to various detinations see below.
Somehow I have configured a separator line under the entry "Renting" but I dont know how I did it.
Any ideas?
This is configured in the "Images" file type group.
I have looked at length but cannot find anything there.
Nothing in the help that I can see.
Any answers greatly aapreciated.

Right-click on Poster and click on Begin a group
