How to check
- Press the “suspicious” keys one at a time.
- See the statistics: if the key is triggered twice with one click, there is a problem.
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.
Reasons for double-clicking on the keyboard
- Wear on switches (especially on mechanical keyboards).
- Contact contamination (dust, moisture, crumbs).
- Oxidation or damage to the contacts on the board.
- Software failures (drivers, OS settings).
- Keyboard defect (defective or low quality).
