Using Virtual Box / Switching between the GUI and CMD
 

How do I switch Terminals? Using the CNTL+ALT+F1, 2, 3, 4, 5, 6 does nothing for me. I am using Virtual Box and Running Red Hat.

Some forum threads I found after a quick search:

And if the HostKey+F[1-12] doesn't work, you're using a non-US keyboad, and you're using an old version of VirtualBox:
