Yes, Semantic does know a good starting point. You can use
to get the tag under point. You can then use
to get a starting point. If no tag under point, you can use
to find the previous tag, whos end point would be a safe starting place.
Semantic uses syntax tables in order to use Emacs built-ins for parsing
data. Semantic could use just about anything I suppose, but since it
overlays the buffer with tag info, that seems the most rational thing to
