Lesson 04: Function Keys (F1–F12) and Laptop Fn Key
List of Topics
In the previous part, we learned typing basics. Now, let's talk about the top row of your keyboard, where keys from F1 to F12 are located. These are called Function Keys.
But there is a twist! These buttons behave differently on Laptops compared to Desktops.
1. Desktop Keyboard: Simple and Direct
Desktop keyboards usually don't have an Fn button. This makes things very simple.
F1: Used to open the Help window.
F2 (Most Useful): Click on a file and press F2; you can immediately change its name (Rename). This is used every few minutes in office work.
F5: To Refresh the computer. If the screen hangs or feels slow, press F5.
2. Laptop Keyboard: The "Fn" Key Puzzle
Laptops are compact, so companies assign two tasks to a single button. You will find a button labeled Fn in the bottom left corner.
2.1 Understanding the Modes
Laptop F1–F12 keys have small icons on them, like Volume Up (🔊) or Brightness (☀️).
Setting 1: Direct Mode
If pressing F1 immediately mutes the sound, it means the icons are working directly. To get Help, you must press Fn + F1.

4. Laptop Multimedia Control
- Brightness: Increase or decrease screen light (☀️+ / ☀️-)
- Volume: Control the speaker sound (🔊)
