You perform one of the following actions in Windows Vista:

• You hold down the NUM LOCK key for more than 5 seconds to turn on Toggle Keys.
• You hold down right-side SHIFT key for more than 5 seconds to turn on Filter Keys.

In either scenario, a dialog box appears, and you are prompted whether you want to enable Toggle Keys or Filter Keys. However, the dialog box does not have the focus as expected. Therefore, you cannot directly give an appropriate response to the prompt.
