KeyBoard Tester:

KeyBoard Tester

Keyboard Tester is a free online keyboard tester that offers you virtual keyboard, which you can use to check the functioning of the keyboard keys. It provides you a text input field where you can type your text and check those keys are working or not. The keys working properly turn to color Green on the virtual keyboard.

Some of the keys on our keyboards are present twice, like, Ctrl, Alt, etc. When you press of any of these keys, this online keyboard tester doesn’t knows exactly which key is pressed, and it highlights all. This is a bit of disadvantage.

Another thing to be kept in mind is that, to check the keys of the numeric pad, you need to ON the “Num Lock” key.
