Host Key Customization

To disable all Host key combinations, open the preferences and change the Host key to None. This might be useful when using in a kiosk mode.

To redefine or disable certain Host key actions, use the following command: 

$ VBoxManage setextradata global GUI/Input/MachineShortcuts "FullscreenMode=F,...."

The following table shows the possible Host key actions, together with their default Host key shortcut. Setting an action to None will disable that Host key action.
