The right arrow key moves the cursor or selected icon to the right one character at a time. The left arrow key moves the cursor or selected icon to the left one character at a time.

Arrow keys are most commonly used with word processors and text editors to move the cursor one character or one line at a time. They are often used to navigate menus and to scroll down web pages or documents.

In addition, arrow keys can also be used to select menu options, activate buttons, and move around within menus and windows. Some computer games also use the arrow keys for game controls.

Arrow keys can be used to move the cursor in any direction. This is a useful tool for making small corrections or for quickly navigating large documents.
