Keyboard Filter and On-Screen Keyboard (POSReady 7)
4/29/2013
On-Screen Keyboard displays a visual keyboard with all the standard keys. Instead of relying on the physical keyboard to type and enter data, you can select keys using the mouse or another pointing device, or you can use a single key or group of keys to cycle through the keys on the screen. However, On-Screen Keyboard bypasses key filters.
Keyboard Filter only supports hardware keyboards. All applications featuring software-based keyboard input will circumvent Keyboard Filter. On screen keyboards are not filtered, including those bundled with Windows. This also applies to any applications that send input using Windows APIs.
Warning
By design, filtering keyboard input using Keyboard Filter may impede accessibility scenarios.
