Yes, I'm referring to things like select item, open-pdf. I recently saw discussion that you can specify specific pages (or maybe annotations?) via URI, and am wondering if there is other URI functionality I am missing (because so far those are very useful!)
you can refer to item and pdf, here some related dicussion,

you can use plugin Zutilo for acessing them as well
Maybe there is documentation for this somewhere?
