Screenkey is an overlay on-screen indicator to show what keys you are typing. It's best for screencasting (making video tutorial) when combined with Kazam Screen Recorder like what you easily find on YouTube. Screenkey on GNU/Linux is a good replacement for Keycastr on macOS and Keyboard Jedi on Windows. It's available on GNU/Linux distros, especially Ubuntu and Trisquel. Here's how to install it and some examples you may find useful for your desktop teaching. Happy recording!
