Thanks Tim, that actually works great. Of course, now I want more...
so if you are up for more read on.
Basically the format for a PDF reference is: "N N R" where "N" is an
integer and "R" is literal. So typically you will see something like a
PDF "Name" (which is prefixed with a "/"), then a reference to an
object reference value for that name. For example
5 0 obj
<<
/Type /Catalog
/Pages 1 0 R
/Outlines 19 0 R
/PageMode /UseOutlines
/Metadata 3 0 R
>>
...
19 0 obj
etc..
The reference "19 0 R" points to a PDF object declaration somewhere in
the file like "19 0 obj". So, right now (thanks to your help) I can
put my cursor over the "19" in the /Outlines reference value, hit F4
and navigate directly to the "19 0 obj". Now... it would be even
better if I didn't have to put the cursor on the id number itself,
just the line it's on. I suppose that would mean navigating to the
first reference ("\d+\s\d+\sR") and then executing the object search
which you just provided.
If you want an example of this sort of text, just open any PDF file in
Vim and look for "/Outlines" or "/Catalog".
BTW... just noticing that characters classes (like "\d" for digits)
don't seem to work in regular Vim "/" searches, is that really the
case?
Thanks!
Scott
