Keyboard Wedge

What is a Keyboard Wedge

A keyboard wedge is an interface that lets a device other than a keyboard connect to a computer and transmit keyboard data. If you wish to hook in a peripheral, like a barcode scanner or magnetic strip reader, and have it give data to the application, you must use a keyboard wedge since most data-entry software is configured to collect data from a keyboard. The physical counterpart of the wedge “wedges” between the keyboard and the computer, hence its name. To allow data entry using either the keyboard or another peripheral, the keyboard is connected to the wedge, which is then connected to the computer.

Keyboard Wedge

When utilizing software with a peripheral it was not designed for, a keyboard wedge can be helpful. While some data entry programs are created with barcode scanners or magnetic strip readers in mind, the majority are created with the assumption that a keyboard will be the primary data entry tool utilized. But since most people can’t read barcodes, many organizations utilize them instead of manually entering the unit code. This necessitated the development of a system for breaking down the barcode into its component information and sending it to the computer as alphanumeric data. In the early days of computing, a programmer at Alter Instruments in Britain invented the keyboard wedge.

What Is a Keyboard

To save the letters, characters, and symbols you need to enter text into a computer or smart phone, a keyboard is available in a variety of formats. Almost every type of computer device uses a keyboard. Although many other hardware manufacturers also make physical keyboards, Microsoft and Logitech are among the most well-known manufacturers.

Keyboard Definition

The keyboard is a piece of hardware that is used with computers and similar devices to input text, characters, and other commands. In a desktop system, it is an external peripheral device that rests outside the computer case, or it is “virtual” in a tablet PC.

Typical Keyboard Description

Modern computer keyboards were patterned after vintage typewriter keyboards, and they still resemble them quite a bit. There are many different keyboard layouts available in the world (including JCUKEN and Dvorak), but the majority of English-language keyboards are QWERTY-style. Other languages have various standard keyboard layouts, as AZERT for French and QWERTZ for German.

The majority of keyboards have letters, numbers, symbols, arrows, etc., but some also have a separate numeric keypad and extra features like volume controls, buttons to turn the device off simply use a set of customizable shortcut keys to put it to sleep.

Physical Keyboard Connection Types

Many keyboards are wireless and connect to computers using RF or Bluetooth.

The USB Type-A connector is frequently used by wired keyboards to connect to the motherboard, however USB-C is also available. Older keyboards use a PS/2 connector to connect. Despite being integrated, laptop keyboards are technically termed “wired” because of the way they are attached to the computer.

Touch Screen Keyboards

Physical keyboards are frequently absent from tablets, phones, and other computers with touch interfaces. Instead, they provide on-screen keyboards for the smartphone. However, the majority do come with USB ports or wireless capabilities that let you connect an external keyboard.

Touch Screen Keyboards

Almost all recent smart phones include on-screen keyboards that appear when you need them, similar to tablets. These touch keyboards and touch screen keyboards are other names for these on-screen keyboards.

Although laptops and net books have built-in keyboards, they may also connect external keyboards through USB, just like tablets.

You can download a variety of software-based keyboards to match the design and operating system of your device. Examples for that OS can be found on our list of the Best Keyboards for Android.

Keyboard Shortcuts

Even though the majority of us use keyboards almost daily, there are numerous keys that you either don’t use or aren’t aware why you use. The keyboard buttons listed below can be combined to create new functions.

Modifier Keys

Modifier keys are a class of keys that you should become familiar with. The Control, Shift, and Alt keys are modifier keys, and you’ll undoubtedly encounter some of these in the troubleshooting instructions on this website. Option and Command are used as modifier keys on Mac keyboards; for further information, see Windows Keyboard Equivalents for the Mac’s Special Keys.

Modifier keys, as opposed to standard keys like a letter or a number, change the behavior of another key. For instance, the 7 key normally inputs the number 7, but if you simultaneously hold down Shift and 7 keys, the ampersand (&) sign is formed.

On the keyboard, keys with two dots represent some of a modifier key’s effects. Measures, such as the 7 key. Shift activates the top action on keys like these, which have two functions.

The keyboard shortcut Ctrl+C is certainly one you’ve used before. It is used to copy content to the clipboard so that you can paste it later by pressing Ctrl+V.

Modifier Keys

Ctrl+Alt+Del is another example of a modifier key combination and can be used to restart a computer, sign out of a program, open Task Manager, and more. Unlike the 7 key, which has usage instructions set out on the keyboard; these keys don’t have as evident functions. This is a typical illustration of how the use of modifier keys can result in a result that none of the keys individually, independently of the others, can achieve.

Another keyboard shortcut is Alt+F4. This one immediately shuts the window you’re using right now. This combination will immediately shut the tab you’re now focused on, regardless of whether you’re in a web browser or looking through photographs on your computer.

Windows Key

The Windows key, sometimes known as the Start key, Flag key, or Logo key, can be used for a variety of purposes in addition to launching the Start menu.

One way to use this key to rapidly show/hide the desktop is Win+D. Another helpful shortcut for opening File Explorer quickly is Win+E. We like the Win+X (Power User Menu)

Changing Keyboard Options

From the Control Panel in Windows, you may modify a few keyboard settings, including the repetition delay, repeat rate, and blink rate.

 Using third-party software like Sharp Keys, you can modify a keyboard in a sophisticated way. This is a free tool that modifies the Windows Registry to deactivate one or more keys entirely or remap one key to another.

If a keyboard key is missing, Sharp Keys is a lifesaver. For instance, if you don’t have access to the Enter key, you can remap the Caps Lock key (or the F1 key, etc.) to the Enter function, basically taking away the functionality of the former key to make the latter key usable again. Additionally, it may be used to assign keys to browser controls like Back, Refresh, etc.

It is called the Microsoft Keyboard Layout Creator Changing the keyboard layout quickly is possible with yet another free utility. The instructions provided by Little Tiny Fish for using the application are clear.


The musical alphabet is referred to as these notes. They serve as the keyboard’s white keys’ names.


There are always two or three black keys together. White key symbolizes the C note. It is always between two black keys on the left side of the keyboard. Locate each and every C note on your piano.

Arabic keyboard

Arabic keyboard

The keyboard layout used for the Arabic script is known as the Arabic keyboard (Arabic: , lawat al-maft al-‘Arabyyah). Latin characters, which are required for URLs and e-mail addresses, are also present on all computer Arabic keyboards. Arabic is written from right to left, so while using an Arabic keyboard, the letters will begin to show on the screen from the right side.
