Overlay of commands / shortcuts / keys pressed - Screencast Mode

[thomthom]

Summary of the new feature/enhancement

It would be great to have a Screencast mode similar to what VSCode features:
https://code.visualstudio.com/updates/v1_31#_screencast-mode

Very useful for making demos and tutorials.

Proposed technical implementation details

I can see the need for some basic control over size and position. Probably font, size, color and position should be flexible enough.

Another consideration I'm not sure how to best address is multiple monitors. Should the key stroke message be displayed on all monitors? Or just the active one? Or a fixed one?
