Using a Mouse
Jyoti: Moz, you said that we could play music using the com-
puter. Can we do that today?
Moz:  Sure, we use a speaker to listen. Can you tell me how 
to select the song?
Jyoti: Using the mouse! We already know that a mouse is used 
to point at items shown on the monitor. When we move the mouse 
around, the arrow on the screen also moves around.  
Moz: Good. The arrow is called the mouse pointer. The mouse is 
usually kept on a flat surface called the mouse pad. Now, how 
do you play the music? 
Tejas: I think we should press the buttons on 
the mouse, but which one?
Moz: Pressing the button is called a click. There are 
two buttons on the mouse. The button on the left hand 
side is called the left button. The button on the right hand 
side is called the right button. Clicking these buttons tells the 
computer what to do.  
There are three types of mouse clicks:
Left click: Click the 
left button once. This 
is used to select an 
activity after you 
point to it.
Double click: Click the 
left button twice, 
quickly. This is used to 
start the activity after 
you have pointed at it.
Right click: Click the 
right button once. This 
is used to control the 
activity after you have 
started it .
