how do i view vertices in particle edit mode to hair along a line?

Thanks everyone for answering my previous question. I got another one tho. How to select vertex groups in particle edit mode. Is there a way to see the lines and vertices of a mesh while still in particle edit mode? or at least the mesh appears solid so i don’t have to relay on wire frame mode to see where to add hair articles? it would be nice to see a vertex group light up so i can simply add hair there? Anyone got any helpful answers? thank you for your time. http://forums.cgsociety.org/images/smilies/grin.gif
