We Bet You Don’t Know The Reason Why Keyboard’s ‘F’ And ‘J’ Keys Have Raised Ridges!


Did you ever look at the keyboard and thought why ‘J’ and ‘F’ keys have raised bumps on them? Sometimes, the same is seen in case of ‘5’ key too. Don’t worry, it is not any kind of production defect, but in fact this is by design.

It is basically for ease of use!

For using this keyboard with ease, the keys have ridges, so that speed typing is possible, without having a look at the keyboard. These ridges help in positioning the fingers. They enable you to have a correct typing position and since the ridges are there on these 2 keys, the index fingers are placed on them.

Know the positioning


If the left index finger is positioned on the ‘F’ Key and if the right index finger is positioned on ‘J’ key, then other 3 fingers of left hand can rest on ‘A’, ‘S’ and ‘D’ and others can rest on ‘colon key’, ‘L’ and ‘K’. Both the thumbs must rest on space bar.
These improvements came in after June E Botich filed a patent in the year 2002. After this, all the keyboards came in with the same arrangement.

In computing, a computer keyboard is a typewriter-style device which uses an arrangement of buttons orkeys to act as a mechanical lever or electronic switch. Following the decline of punch cards and paper tape, interaction via teleprinter-style keyboards became the main input device for computers.

A keyboard typically has characters engraved or printed on the keys and each press of a key typically corresponds to a single written symbol. However, to produce some symbols requires pressing and holding several keys simultaneously or in sequence. While most keyboard keys produce letters, numbers or signs (characters), other keys or simultaneous key presses can produce actions or execute computer commands.

Despite the development of alternative input devices, such as the mouse, touchscreen, pen devices, character recognition and voice recognition, the keyboard remains the most commonly used device for direct (human) input of alphanumeric data into computers.

In normal usage, the keyboard is used as a text entry interface to type text and numbers into a word processor, text editor or other programs. In a modern computer, the interpretation of key presses is generally left to the software. A computer keyboard distinguishes each physical key from every other and reports all key presses to the controlling software. Keyboards are also used for computer gaming, either with regular keyboards or by using keyboards with special gaming features, which can expedite frequently used keystroke combinations. A keyboard is also used to give commands to the operating system of a computer, such asWindowsControl-Alt-Delete combination, which brings up a task window or shuts down the machine. Acommand-line interface is a type of user interface operated entirely through a keyboard, or another device doing the job of one.
