I didn't know about find-file-at-point, so I'm glad I read this thread,
but I don't think that answers the original question. The original
question, I believe, is if you have code like
and you have the cursor on foo(), is there a way to jump to the
definition of that function if the definition is not in the current file?
I think it can be done if you use ctags (or etags?). I'm not a guru by
any stretch, so there may be another way. Or I may just be wrong.
