Taken from RFE 928027: advanced snap features *Snap to Endpoint *Snap to Midpoint *Snap to Intersection *Snap to Apparant Intersection *Snap to Extension *Snap to Center (already in SVN) *Snap to Quadrant *Snap to Tangent *Snap to Perpendicular *Snap to Parallel *Snap to Insert *Snap to Node *Snap to Nearest *Snap to None (Cancel Snap)
The descriptions given of each snap mode in this RFE are quite useful! Thanks for referring to it, I hadn't seen it yet. To answer your question: Inkscape only snaps to path nodes (i.e. endpoints) and to an object's transformation center (not exactly the same as AutoCAD's center). And of course it snaps to boundingboxes, paths, guides, and grids.
One day we might have some of the CAD snapping modes in Inkscape, but don't get too excited yet: it will take time and there are some other things that have a higher priority...
