When reading papers, what's the most convenient way to check a citation without disrupting the reading process? Papers can include clickable-link formatting with in-text citations.  It's convenient to click a link to check the citation, however, it's disruptive to have to manually scroll back up to continue reading.

Is there an easier way to resume reading after checking a citation?  Alternatively, is there a less disruptive method for checking a citation?
If you're using Adobe Acrobat Reader (which I suspect you are), you can press alt + left to jump back to where you were before clicking the link. I find it amazingly useful.
