Mouse
Mouse is a standard hand-held pointing device that helps to select any object on the screen. It is also used to
draw, move and resize the objects, pictures, etc. on the screen. A mouse primarily consists of three parts: the
buttons, the handling area, and the rolling object. By default, the mouse is configured to work for the right
hand. Left-handed people can change the settings as per their needs.
Usually, a ‘Mouse’ has two buttons on it. Generally, the left mouse button is used for doing common tasks on
screen but in some cases, the right mouse button is also used.
The mouse pointer changes its appearance based on its function and location on the screen:
The standard mouse pointer appears as an arrow when you move it around the screen. It can be used
to interact with objects and navigate the interface.
When the mouse pointer hovers over text, it typically changes to a text insertion cursor, indicating you
can type or edit text in that area.
In web browsers, the mouse pointer changes to a pointing hand symbol when hovering over a hyperlink.
Clicking the left mouse button once will follow the hyperlink, directing you to another page.
These different pointer shapes help users identify the current function or action they can perform, enhancing
navigation and interaction on the computer.

How to Use the Mouse?
Place the forehand over the mouse. Hold the mouse by putting your palm on the body of the mouse, such that
the index finger is on the left button and the middle finger is on the right button. Move the mouse slowly over
the table or over the mouse pad. When you move the mouse, the pointer on the screen moves accordingly.
Mouse Operations
Not all mouse operate in the same way, but they all accomplish the same tasks. Some use a tracking ball
underneath, while others use a light beam to track movement. Laptops often have a small flat surface or a
short stick that functions like a mouse.
Most mouse have two or three buttons on top. The left button is used for selecting, dragging, moving, and
pasting items. The right button opens a menu with options related to the item you clicked on, like copying or
deleting. These buttons make it easy to navigate and interact with your computer.
