For example, to get a capital letter ‘A,’ you need to press the Shift key and the A key at the same time. When reading or writing instructions for how to accomplish a particular task, this would be described as ‘Shift + A.’ As another example, in most software applications, Ctrl + S means to save the current document. If you have been using computers for some time, you are probably familiar with a number of such combinations.

The most widely used layout in the English language is called QWERTY, named after the sequence of the first six letters from the top left. Anti-ghosting is an essential feature, allowing a keyboard to register multiple keystrokes hit at the same time—a feat not all standard keyboards can perform.

Why Is The Keyboard An Input Device?
The design is so good that anyone could fall in love with the keyboard. Tablet users also need a keyboard to ensure they type faster when required during work or study, which is easier on a keyboard than an on-screen version.

Projection keyboards can simulate a full size keyboard from a very small projector.
I also have some quibbles with the bulky black backbar which gets in the way if you use it as a phone keyboard, and the 85cm USB cable, which seems far too short.
