Hi, there.
CTools has the newest and most powerful modification to Screencast Keys.
However CTools has already stopped the development recently.
Screencast Keys add-on is useful for making tutorial, so I ported Screencast Keys add-on from CTools.
Screencast Keys use deprecated “bgl” module, so we can not use it no longer after Blender 2.8 will be released. So, I will also tackle to support Blender 2.8 as well.
Currently, Blender 2.8 does not show final Python API specification. I will tackle to this project when Python API sepecification is released.
Thanks.
