Is there a widget for an on screen keyboard? Did not found one.
If not: Is it possible to get an existing on screen keyboard work with Captivate? Like this one: https://mottie.github.io/Keyboard/
Only needs to work in HTML5-output. And would even use something i had to put myself in this output at the end and out of captivate
Have you tested a typical Text Entry Box in Captivate HTML5 output on a mobile device? That would normally automatically call up the device's default on screen keyboard to enable the user to enter text. Why do you need to get a widget to do this?
Why do you need the keyboard. In a Captivate course the learner can type in a Text Entry Box, in the Scrolling Text Interaction and eventually in the Notes widget. I think that in those cases the screen keyboard automatically appears.
