How to test your keyboard capability

The keyboard is one of the devices that we use frequently while using the computer.
Here I provide some way to test if your keyboard is really reliable or not.

You simply type in the phrase "the quick brown fox jumps over the lazy dog" but in ways as follows:

1. Open notepad.
2. Press and hold the left shift key and right shift.
3. Type the sentence "The quick brown fox jumps over the lazy dog". (Note the left shift key and right shift not 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 you 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 that involve all the letters in the English alphabet.

on the keyboard that I use all the letters do not appear
