Configure confirmation on reset of guest by shortcut key

[fridz]

How can I configure that a confirmation is needed when you press the keyboard shortcut for reseting a guest?

At some point I reset a guest machine which gave me a helpful confirmation dialog, asking whether I was sure I wanted to reset the guest machine. There was also a checkbox where I could specify something like "Do not show this dialog again".

Unfortunately I checked this checkbox and now when ever I press CMD + R the guest machine resets. Is there a way to get the confirmation dialog for guest resets again?

The location varies between host type and version but there is a "reset all warnings" in the top title bar of the guest where all VBox functions are.

Just to clarify, For the OSX version it's in the VirtualBox VM menu in the Apple menu bar.
