Is there anything in LinkFunctions.php that would help me construct a link from the items/show page back to the specific page in items/browse that contains the item I am currently showing. In other words, I want to add another link following my next/previous links that says "Return to Browse". This link wouldn't go to the beginning of the browse, but rather to the specific browse page that contains the item I was just looking at (even if that is a different item from the one I originally clicked on in the browse screen because I have been using next/previous to step through some items from my current browse context).
Note that I have already implemented a custom next/previous to step through a search, a single collection, or the list of recent items from the home page (in addition to the usual browse all). So my next/previous function already knows the context for the current item, including its id and it's position in the get_items list for that context. Do I need to calculate a page number somehow and build the url for the "Return to Browse" from scratch?
