'Drag-along-surface' shortcut?

[svdelle]

I've created an inset on a poly (b). Now I would like to drag two of those points on the newly created poly along the surface of the original poly - kind of shrinking the new poly along the surface of the original poly. This would be no problem had the poly been lying flat on the 'ground' pointing in either the z- or x- direction. But I have this this floating around in space, and need this little trick to 'drag along surface'.

Any hints?

maybe "normal move" from Mark Brown on http://www.spatial-design.com/plugins/ is the one you are looking for?

EDIT: ooops... you said "two POINTS" ... ok... delete me :P
