🖥️ Comprehensive Keyboard Keys Table (Windows 104-Key Layout)

A keyboard is the most essential input device used with a computer. It acts as a bridge between human thought and digital action. The Windows 104-Key Layout is the standard keyboard design used across desktops and laptops today. Each key plays a unique role, and understanding their purpose helps improve typing speed, productivity, and accuracy.

🔤 Overview of the 104-Key Keyboard

The 104-key keyboard includes a combination of alphabetic, numeric, function, navigation, control, and special keys. Every key is strategically placed to ensure smooth interaction with software, games, and applications. The layout is designed to support multitasking, data entry, editing, and quick access through shortcuts.

🧩 Categories of Keys

Here’s a quick look at the different types of keys and their uses:

1. Alphabet Keys (A–Z)

There are 26 alphabet keys used for typing letters and words. These are the most frequently used keys and can be combined with the Shift key to produce uppercase letters.

2. Numeric Keys (0–9)

The number keys are placed on the top row of the keyboard and on the numeric keypad. They are used for entering numerical data and performing mathematical operations.

3. Function Keys (F1–F12)

These keys perform specific actions depending on the program in use.

• F1 opens help,

• F5 refreshes the page,

• F12 opens the “Save As” window in Microsoft Office, etc.

4. Control and Modifier Keys

Keys like Ctrl, Alt, Shift, and the Windows key modify the behavior of other keys. For instance, Ctrl + C copies text, and Alt + Tab switches between open applications.

5. Navigation Keys

Keys such as Arrow keys, Home, End, Page Up, and Page Down are used to move the cursor within text or documents without using a mouse.

6. Editing Keys

Keys like Backspace, Delete, Insert, and Enter are essential for text editing and document formatting.

7. Special Character and Symbol Keys

The top numeric row also includes symbols like !, @, #, $, %, ^, &, *, (, ), etc. These are accessed by holding down the Shift key.

8. Numeric Keypad

Located on the right-hand side, this section is useful for fast numeric data entry, especially in accounting or spreadsheets.
