Hey, that's really cool. But, I have to move the mouse in order to get
the help-echo to display. Is there anyway to get the help-echo to
display without the mouse (either automatically once you've done
"C-S-n" or with a key)?

Ok, I deleted the doc.txt file for PCL and did a "C-u doc-view" to
re-generate the PDF; however, search still doesn't work properly with
PCL. I just did a simple search for "mapcar". When I press "C-S-n",
the first page it positions to is physical page 51 (page 25 in the
book). However, "mapcar" isn't on that page. The first match is
actually on physical page 57 (page 31 in the book) and that
corresponds to the matching text that is displayed by doc-view for
physical page 51 ("specify the values to change. The main new bit is
the use of a function MAPCARthat maps over").

Presumably, if you search for "mapcar", you are positioned to physical
page 57?
