The Backspace key (also known as the delete key) erases the character to the left of the cursor.

The Enter key (also known as the return key) executes commands. For example, while on the Internet, you can type a website address and then press Enter to go to the site. It is also used to start a new line in word processing programs.

Insert: This switches between insert mode (which inserts new text without deleting anything) and overtype mode (which deletes text after the cursor as you type).

Delete: This erases the character to the right of the cursor.

The numeric keypad resembles a calculator keypad. Many users find that it is easier to type numbers using this keypad. On some keyboards, these keys double as arrow keys.

The Arrow Keys are used for many different purposes, including moving the cursor, scrolling a document, and controlling a game.

The main part of the keyboard includes the alphanumeric keys (letters and numbers) and the spacebar.

The Control (Ctrl), Alternate (Alt), and Shift keys are designed to work in combination with other keys. Typically, you hold down Ctrl, Alt, or Shift and then type another key to perform a specific task. For example, in many programs, typing Ctrl+S will save a file.

The Tab key is used to create indents in word processing programs. Also, if you are filling out a form online, you can use the Tab key to switch to the next field.

The Escape (Esc) key allows you to stop a function or action. For example, if a webpage is taking a long time to load, you can press the Escape key to stop loading it.

The function keys are labeled F1 through F12. Some programs use these keys as shortcuts for common tasks. For example, in many programs, F1 opens the Help file.

These move the cursor to the beginning or end of the current line.

These scroll a document or webpage up or down.
