A computer keyboard is an input device that allows users to enter data and commands into a computer. It consists of keys arranged in a specific layout, typically including:
- Alphanumeric keys: Alphanumeric keys on a computer keyboard are the keys that represent both letters and numbers. These keys include:
- Letters (A-Z): The uppercase and lowercase letters of the English alphabet.
- Numbers (0-9): The digits used in numerical input.
Alphanumeric keys are the primary keys used for typing text and data. On most keyboards, these keys are arranged in a QWERTY layout, which is the most common layout used in English-speaking countries. In addition to letters and numbers, many alphanumeric keys also have special characters accessible via the Shift key.
- Function keys: Function keys are a set of keys on a computer keyboard that perform specific tasks, typically labeled F1 through F12. Each key can have different functions depending on the software or operating system in use. Here are some common uses for function keys:
- F1: Often used to open the help menu in many applications.
- F2: Commonly used to rename a selected file or item.
- F3: Typically opens a search function.
- F4: In many programs, it can close the current window (Alt + F4).
- F5: Often used to refresh a page or document.
- F6: Can move the cursor to the address bar in web browsers.
- F7: Often used for spell check in word processors.

The functionality of these keys can vary widely based on the context, so checking the specific software's documentation can provide additional insights.

- Shift: Used to type uppercase letters and access the secondary functions of keys (like symbols on number keys).
- Ctrl (Control): Often used in combination with other keys to execute commands (e.g., Ctrl + C to copy, Ctrl + V to paste).
- Alt (Alternate): Used for accessing alternative functions or shortcuts in various applications (e.g., Alt + F4 to close a window).
- Cmd (Command): Found on Mac keyboards, it serves similar functions to Ctrl, allowing users to perform commands (e.g., Cmd + S to save).
Modifier keys enable keyboard shortcuts, making it faster and more efficient to perform various tasks without relying solely on mouse input.
