💻 Class 1 Computer – Chapter 5: Using a Mouse
🔹 1. Introduction
A mouse is an important part of the computer.
It helps us to point, click, and move things on the screen.
The mouse is a small device that fits in our hand.
It looks like the small animal called a mouse, that’s why it has the same name! 🐭
🔹 2. Parts of a Mouse
A computer mouse usually has three main parts:
🖱️ (1) Left Button
-
Used to select or open things on the screen.
-
We click this button once or twice.
-
Example: Double-click the Paint icon to open it.
🖱️ (2) Right Button

Used to open menus or get more options.
-
Example: Right-click on the desktop to see a list of commands.
🌀 (3) Scroll Wheel

2️⃣ Keep your palm on the mouse.
3️⃣ Keep your index finger on the left button.
