Ctrl-Alt Hotkey Conflict with Virtual Machines

On most virtualisation software like VMWare’s etc, the guest machine’s hotkeys which requires ctrl-alt (such as ctrl-alt-f1 etc for tty change in Linux) can be blocked because ctrl-alt is used to release mouse/keyboard with the VM software. If you use it only occasionally, you can first temporarily disable the release hotkey by pressing ctrl-alt-space then your intended hotkey such as ctrl-alt-f1
