We all use computers as the sophistication of the technology. A huge number of people all around the world use computers daily. But there is a secret hidden in this computer keyboard that you use every day. What actually is this?
Look at your computer keyboard carefully. There are many keys in the same size and some are longer than the others. If you look carefully at F and J keys you will be able to find two bumps on them. Most of the people don't pay any heed at these bumps.
Do you know the objective of these bumps? The reason is you have to use both of your hands when you are typing. When you are typing you have to keep your left finger tips on letter F and right finger tips on letter J. This will help you to type more accurately and it saves the time too.
