I'm including \usepackage{hyperref} so that each instance of \ref (as well as each page number in the index and the table of contents) automatically links to that page.
When I'm viewing the document (in Sumatra) and I click a link, I jump to the linked page. Is there any easy way to go "back" to where I was before I clicked the link? (And is the answer any different when using Adobe Acrobat reader?)
