>So is the PDF reader (and searchable reader)
The reader is free, the proprietary file format isn't. Also, Acrobat is only
searchable from within Acrobat. There is no way to start Acrobat with a
search for an external program. If it did that (or if it does that and I'm
not aware of it), then it would be fine. Maybe there is a way? Do you know
of one? If I'm in my editor (whatever that may be, on Unix, Win, or Mac),
and I want to quickly look up the parameters for DmDatabaseInfo, I just want
to be able to park my cursor on the function, hit a key, and have WHATEVER
bring up the documentation for DmDatabaseInfo. I don't want to have to find
Acrobat among my dozen running programs, bring up the search dialog, and
type the function name in again (ok, I'm lazy, but it's one less place for
me to goof up). Then, chances are that the first search is going to bring up
some other reference to DmDatabaseInfo, and maybe another, until I finally
get to the actual definition. If Acrobat could jump directly to the
definition (maybe by jumping to whatever keyword has been copied into the
clipboard, etc???) then I would be a happy camper.
