Ctrl+shift for selecting elements in a mesh

I’m having trouble with rihno 5 on parallel’s mac for selecting elements in a mesh, ctrl+shift won’t work, does anyone have a solution, maybe there is something I’m missing. thank you

Which versions of Mac hardware, OSX, Parallels, and Windows Rhino?

McNeel doesn’t officially support Windows Rhino running under virtual machines, so don’t expect them to research the issue for you. If they happen to already know the answer, I’m confident they will pass it on to you. Otherwise any help will come from users, if any, who have overcome the concern.
