Your Mouse Can Be a Very Versatile Helper

Your Mouse Can Be a Very Versatile Helper

The mouse gives you control over your computer.
With the mouse in your hand you cause the
onscreen arrow
to move around your computer display. It is
based on the
“point and click” philosophy. You move your
mouse to a
point where you want something to happen, then
click to make that event take place. Sometimes
you click once.
Sometimes you click twice. And sometimes you
hold down
the mouse while your event is happening.
Most mouse devices give you two opportunities
for clicking.
 There are both right and left areas to depress.
The left area is generally used for issuing
commands to your
computer. To access special menus (known as
sensitive menus) use the right portion of your
When you use your mouse for word processing, you will find that it sometimes changes shape. Please look at the example on the right. By default there is a white arrow that points to the left or right. This enables selection of command options.
Pressing down on the left-mouse twice in rapid succession produces adouble-click. Generally you double-click to open an onscreen object. In this illustration the "My Computer" object to the right is dimmed, indicating a single click has activated it. If you click on the dimmed object, your action will open the file represented by that object.

Sometimes the mouse makes things happen simply by moving
around the screen. A mouseover occurs when an onscreen image
 changes as your mouse travels over it. In the example to the right
 the active link will change color as you move your mouse over it.

As you practice with your mouse you will notice two other characteristics. Once is the concept of key depress and key release. By clicking once (depressing the left mouse, then immediately releasing it, you cause an onscreen event to happen). In the Flash animation file to the right, use your mouse to depress once and release on any of the buttons. The key depress action causes an onscreen event to take place.
You can also sometimes click and hold down the 
left mouse.
This would be the case when you want to highlight a
section of
text by moving the mouse over it, or when you want
to move an
onscreen object using your mouse. In the example to
the right
 you would left-click, then hold down the mouse while
drag across the area you wish to highlight.
