Below are instructions to enable the onscreen keyboard when displaying your laptop onto the promethean board. This grants the ability to type using touch keyboard on the Promethean screen instead of having to type on the keyboard.
Open settings (click the windows start button and type settings) once settings is open click Time & Language, Typing, Touch keyboard, and select the checkbox in the list that says Show the touch keyboard when there’s no keyboard attached.
If these settings do not initially show up leave your computer connected to the dock and restart. Login and run through the instructions again.
