Directional key

What does Directional key mean?

A directional key, also known as an Arrow key or cursor key, is a key on a keyboard that is used to Move the cursor or insertion point in a specific direction on a computer screen. There are four directional keys: up, down, left, and right. They are typically located on the bottom-right corner of the keyboard, in the same row as the spacebar.

Directional keys are used for a variety of purposes, such as navigating menus, scrolling through documents, and playing games. They can also be used to enter text in some applications, such as text editors and chat programs.

Directional keys work by sending a signal to the computer’s operating System, which then moves the cursor or insertion point in the specified direction. The distance that the cursor moves is determined by the operating system’s settings.

Applications

Directional keys are an essential part of the user interface for many computer applications. They allow users to navigate menus, scroll through documents, and select objects easily and quickly. Directional keys are also commonly used in games, where they are used to control the movement of a character or vehicle.

In addition to their use in computer applications, directional keys are also used in a variety of other devices, such as remote controls, calculators, and cell phones.

History

Directional keys were first introduced on the IBM Model M keyboard in 1984. Prior to this, users had to use the Tab key to move the cursor in a specific direction. The IBM Model M keyboard also featured a dedicated Home Key and End key, which allowed users to move the cursor to the beginning or end of a Line of text, respectively.

Directional keys quickly became a standard feature on keyboards, and they have remained so to this day. They are an essential part of the user interface for many computer applications, and they are also used in a variety of other devices.
