Software to show typed keys on the screen

Question

Just as the capture shows, when you type something using the keyboard, a big label appears at the bottom of the screen showing the keys you typed.

I use Windows & Linux, so I just want to know if there is a similar software to do that?

Answer 1

There is Key Jedi

Key Jedi allows learning and training to use keyboard shortcuts. It can be used in presentations, screencasts and videos, as well as when working with someone else on the same machine to teach new shortcuts. It shows a visual list of shortcuts as you type them, no matter what application you work in. It is free, simple and quick to use.
