Keyboard Test Capability

The keyboard is one of the devices we use often when using a computer.
Here I give a few ways to test whether your keyboard is really reliable or not.

You simply type the sentence "The quick brown fox jumps over the lazy dog" but the following ways:

1. Open your notepad.
2. Press and hold the left shift and right shift.
3. Type the sentence "The quick brown fox jumps over the lazy dog". (Note the left shift key and do the right shift off).
4. See if writing out complete accordance with the words above or there are missing letters.
5. The more letters that do not come out, then the bad quality of your keyboard.

Why should write the sentence "The quick brown fox jumps over the lazy dog"?
Because of these words is a sentence that contains all the letters in the alphabet which is used to test typewriters and computer keyboards, and in other applications involving all the letters in the English alphabet.
