I have to use the On-Screen Keyboard of Windows 7 for typing:

(In case you haven't used it yet, you can get it via: All Programs -> Accessories -> Ease of Access -> On-Screen Keyboard

or simply search for "osk.exe")

It offers a feature to "hover" about the buttons. Microsoft describes it as the following:

In hovering mode, you use a mouse or joystick to point to a key for a predefined period of time, and the selected character is typed automatically.

There is my specific problem. The predefined period of time is too long to be useful for me. The minimum amount of time is 0.5 seconds (max. 3 seconds).

Is there any way to alter this value to something < 0.5? For example via editing the registry?

Edit: The entry *'HKEY_CURRENT_USER\Software\Microsoft\Osk\HoverPeriod'* cannot be set lower than 500 ms.

Any helpful tip would be great!
