Hello, Thank you for taking the time to report this. The actual problem is that you have to use the keys from the numeric keypad instead of the normal number keys. You can change this manually, to use the key on the character pad, but it again stops working after a restart. If I remember correctly, this is a bug with all default shortcuts.
