Copy Shape Verts

Browse Source 
In mesh editmode, while editing a shape, select some verts, W Key, "Copy Shape Verts". You will be presented with a list of shapes and once chosen, the selected verts will be moved to the position of the verts from the chosen shape. Most handy use would be reverting part of a shape back to basis e.g.

Making eyebrow shapes, add a key and model the eyebrow shape symetrically with the x-mirror tool
Go out of editmode, copy that shape
Go into each shape and revert 1 side to basis

If the mesh has had verts added/removed since last entering editmode, you need to TAB-TAB first before copying
