tags only work on the files indexed so the gnome stuff won't work.  I
just use a web browser and look at the online docs most of the time.

To jump to a scheme def from C you can make sure you are trying to
find "(gnc:main)" (with parens without quotes :).  Not the nicest way
to do it, but it seems functional.
