So you can write a function that asks for the page number, and adds something like this to the doc-view-mode-hook, after cleaning up any previous such setting. Then add it as a -before advice to find-file. I tested the hook setting but not the rest of it: caveat emptor. -- Nick "There are only two hard problems in computer science: cache invalidation, naming things, and off-by-one errors." -Martin Fowler
