SUMMARY Showscreen and wshowkeys are two applications to display the current typed characters as an overlay on the screen, which is useful if you want to demonstrate something which involves inputs to someone else e.g. via a video. Unfortunately showscreen only runs under X and wshowkeys is no longer actively maintained or developed. It'd nice if there were a native effect in kwin which gives the same functions without relying on external applications.

A good example of a legitimate app that the current Wayland protocols don't adequately support. We might be able to add a native KWin effect for something like this, or else work upstream to try to find a way to make apps like this work on Wayland.
