It takes about 3 seconds to understand how this tool works. However, I will quickly discuss how it is used. Usually, software programmers need to explain how things work. After being associated with a web page, all you have to do is push the spacebar. Each time you push it, start counting down the counter. If you want to measure your speed, I suggest running a timer before you start pushing the spacebar. The restart switch also allows you to reset the checking process. The space bar clicker tool is easy to use. Please call me if you have problems using it in your internet browser. Let me explain to you how it is used.
