Remote Session: Switching from Desktop to Metro Mode Windows Server 2012

I'm having a terrible time switching back/forth between the desktop and metro mode in remote desktop windows accessing a Windows 2012 server.

I know of two ways–one doesn't work in remote session windows and the other works very, very, poorly:

1. Using the "hot zones" at the very right edge of the screen–hard to hit when the right edge of the "screen" is just the edge of a remote session window with nothing to "stop" the mouse against.
2. Press the "Start" button–brings up my PC startmenu rather than the remote session start menu.

Are there any other ways?
