New uv system in 246/247

Does anyone know how or if it is possible to select the uv section of a mesh that is bounded by a seam in the new uv system in 2.47, with out selecting all the rest of the mesh at the same time? If anyone Knows how I would appreciate the help, Thank you.

Make sure you are using Face select (Ctrl-Tab / face) and then place your mouse over one of the faces in the section you want and press L (linked). This should select the entire island.

Thank you, that is what I was looking for.
