So I've got the hang of adding keys to HKEY_CLASSES_ROOT\Directory\Background\Shell, and I know I can add a string entitled 'Position' and change its value to position the entry I've made, but I can't figure out how to do three things (nor can I find anything guiding me in doing them):
1) How to put a bar on either side of an entry to separate it from other entries
2) How to position them in an exact place in the context menu (eg. above or below a certain other entry)
3) How to make an entry that brings up another list of entries (like the 'View' and 'Sort by' entries that are already there when you right-click in Windows Explorer
I wasn't sure whether this goes in StackOverflow or SuperUser, but I thought maybe it goes here since I'm using Regedit rather than coding it (though I am aware you can right a .reg file and then execute it to install these sorts of things). Thanks!
