Keyboard usage with flight simulator

The CTL + (num) Del key do not seem to work for parking brake .

The (num) Del key do not work for brake on runway.

Cessna 152

I thought the same thing and struggled with it for a while. The actual key combination for the parking break is [CTL]+[* key on the number pad].

Thank you. So the Brake key on the runway is * on the (num) keypad?
