What is a double click on the keyboard?

Double clicking (double tapping) of the keyboard is a common problem in which a single keystroke registers as two or more signals. As a result, two characters appear instead of one (for example, “nn” instead of “h”), which makes it difficult to type, play or work.

How does double click work?

When printing, extra letters appear (for example, “hhello” instead of “hello”).
In games, the character or the camera twitches due to the double firing of the keys.
When entering a password, the system does not accept it, as extra characters are entered.
