Using the Mouse
Microsoft Windows is designed so that you can use a mouse in conjunction with the
keyboard to operate your computer. This document describes how to hold and use a
mouse and how to (if necessary) change some of the mouse settings to suit your
preferences.
You can use the keyboard instead of a mouse for all actions in Windows as outlined in
the Keyboard Help Document.

Using a Mouse
Its name is derived from its shape, which looks a bit like a mouse with its connecting
wire to be the mouse’s tail, and the fact that one must make it scurry along a surface. The
mouse is a computer interface and an alternative to using the keyboard. You use it to tell
the computer what you want to do. The mouse uses a roller ball to transfer the movement
of the mouse on the mouse pad to the cursor on the screen. The roller ball you can see on
the bottom of the mouse rolls against tiny roller balls inside the mouse. There is one that
rolls up and down. And one that rolls left and right.
The cursor has several different shapes depending on the application you are using. Three
common cursor shapes you will use frequently are the pointer, the I-beam and the
crosshair; the most common being the arrow ( ). The shape of the pointer is an
indication of the type of operation that can be carried out at that time. The pointer shape
has a hot spot at the tip of the arrow that is the active area. This hot spot must be on the
button, text, command, etc. to activate it.

Holding the mouse
Place the heel of your hand on the mouse pad and
gently roll your hand over the mouse to cup it
comfortably in your right hand so that your index
finger rests on the left mouse button and your
middle finger on the right button.
The left, or primary, mouse button is used for
normal functions like selecting and the drag-and-
drop feature. The right, or secondary, mouse button
is used for context menus and special drag-and-drop
functions.
Keep the mouse and mouse pad away from the edge
of your desk. This will allow you to rest your arm
on your desktop as you work. This will allow for greater control of the mouse and better
ergonomics so you are comfortable and less strained.
If you want to use the mouse with your left hand, you can swap the use of the mouse
buttons so that the index finger of your left hand is used with the right mouse button and
the right button becomes the primary mouse button (See Reconfiguring the Mouse).
Many left-handed people have adapted to using their right-hand to manipulate the mouse
to avoid the change.

Reconfiguring the Mouse
   Warning: Do not change any Control Panel settings that you do not understand the
      purpose of; otherwise your computer may no longer function as expected.
    1. On the ! Start menu, from the Settings menu, choose Control Panel.
    2. In the Control Panel window, double-click on Mouse.
    • To change the button configuration (right-handed or left-handed), on the Buttons
       tab, choose Right-handed or Left-handed.
    • To change whether you single-click or double-click to open a file or folder, under
       Files and Folders select either Single-click to open an item (point to select) or
       Double-click to open an item (single-click to select).
    • To adjust the speed at which double-clicking is effective, under Double-click
       speed, move the slider to match the speed you need. To test, double-click the
       Jack-In-The-Box. If Jack pops out or in, you’ve double-clicked at the correct
       speed.
    • To adjust how fast your cursor moves across the screen when you move your mouse
       (sensitivity), on the Motion tab, under Speed, move the slider to Slow or Fast.

Mouse operations
Windows uses icons (small pictures) on the screen to represent objects that can be used or
manipulated, menus (from which options can be selected that carry out particular tasks)
and dialog boxes (that request further information from you). The mouse is used to select
and manipulate objects, choose options from menus and respond to dialog boxes.

The different mouse operations are:
Point. Move the mouse so that the mouse pointer rests on the required object (for
example, an icon, name of a menu, button in a dialog box, character in a document, shape
in a picture). If the pointer is an arrow, the tip of the arrowhead must be on the object. If
after some practice you still have difficulty pointing with accuracy it may help to reduce
the mouse sensitivity (see Reconfiguring the mouse).
Click. Tap the left mouse button. If the button is not specified, always use the left button.
Clicking selects an object. If you select a command, and there are no other options
available, the command is run.
Double-click. Click a mouse button twice in quick succession. Do not move the mouse
between clicks. Double-clicking usually selects an object and activates an operation. For
example, double-clicking on an application icon runs the application. If after some
practice you still have difficulty double-clicking it may help to reduce the double-click
speed (see Reconfiguring the mouse).
Right-click. In Windows, clicking with the right mouse button generally gives a shortcut
(context) menu of options relevant to the particular object pointed at when the right
button is clicked. Such context menus can be very useful and you are recommended to
get into the habit of frequently using the right mouse button when using Windows. If you
use the right mouse button to drag-and-drop, you’ll get options to either copy, move, or
create a shortcut. This is the recommended way to move, copy and paste objects or text.
Click-and-Drag or Drag-and-Drop. Point at an object, press and hold down the mouse
button, move the mouse to a new position, then release the mouse button. Dragging is
used to select a section of text or objects and to move objects to a new position. Can be
used with the left or right mouse button.

Some Mouse Tips
It is worth using a proper mouse pad, as the mouse may not respond smoothly if used on
a hard or slippery surface.
Don’t abuse the mouse. If a mouse is pounded on the desk or if you jab at the buttons, the
mouse may move while clicking creating unexpected or unwanted results.
It the mouse reaches the edge of the pad or table before reaching the end
of the movement you intend, lift it and reposition it. It’s the tracking ball
on the bottom of the mouse that dictates the actions of your cursor. If the
ball doesn’t move, neither does the cursor.
If the mouse pointer responds erratically, the mouse-ball may need
cleaning. With the power to the computer turned off, turn the mouse
upside down and release the ‘trap’ that holds the mouse ball (as
indicated on the mouse casing). Remove and clean the mouse ball with
warm water (do not use a harsh solvent such as alcohol) and then dry it
thoroughly with a clean cloth. Using a cotton swab with some tape head
cleaning fluid carefully wipe the ball rollers inside the ball socket.
Replace the mouse ball.
