KmCaster is a free software to capture real time mouse and keyboard events for screencasting. This is an open source tool that even works with emulation software, and you can use it to showcase whatever keystroke you are pressing in real time in your video recording or live streams. It accurately captures all the mouse and keyboard events and shows them in a pop-up like window that sits on top of your desktop.
There are many other software for doing the exact same thing, but they don’t really capture the keyboard and mouse events in real time as KmCaster does. This is a cross-platform and you can use it in the same way on Linux, macOS, and Windows. It can easily be positioned on your desktop screen and is capable of showing single events as well.
