I use a wireless keyboard on my main computer, and yesterday I had a key that was sticking. In an attempt to find it, I opened my text editor, hoping to catch the key press. Alas, it was not a key that would type anything into text.
So off to the Package Manager I went, looking for a way to find my sticking key.
Enter the Keyboard Status Monitor:
It’s a simple little utility that does nothing more than show your key presses. With the monitor running, it was easy to see that my left hand [ALT] key was the one that was sticking every now and then.
Here’s a demo of the monitor in action:
To install it, just search for key-mon in your package manager or from a terminal window, type: sudo apt-get install key-mon
