Invented in 1963 by Douglas Engelbart, the computer mouse has developed
over the years and now comes in a variety of designs. It’s called
‘mouse’ because it has a basic mouse shape and the cable that attaches
it to the computer looks like a tail. When referring to the device in
the plural, both ‘mice’ and ‘mouses’ are acceptable, according to the
Oxford English Dictionary.
Mice were first made with two gear wheels to define direction and then
with a ‘trackball’, all of which moved in contact with a surface. Today
optical mice that use light to detect direction are more common. Mice
can also be cordless, making them easier to move.
Follow these step-by-step instructions to help you get to know your mouse
Step 1: Pick up your mouse and have a look at it.
At the front (which points away from you), there are two buttons – left
and right. You press or, more correctly, ‘click’ these to make things
happen.
Most mice also have a wheel in between the buttons that you roll to move
up and down the screen – technically called ‘scrolling’.
Step 2: Learn to hold your mouse comfortably. It’s normally held between your thumb and little finger like this:
Step 3: Have a click. Use your index finger to click the left button and your middle finger to click the right button:
If you’re left-handed, you can use the opposite fingers. However, you
can also usually change the preferences on your computer to swap which
buttons do what.
Step 4: Try a double-click. This is done quite often
on the left button. You have to click twice, as quickly as possible. The
first click tells the computer that you are in a particular ‘window’,
and the second click tells it that you’re selecting a button or link or
whatever to do something in that window. If you click too slowly, the
computer just thinks you’re telling it where you are again and again, so
do click quickly.
Step 5: It’s time to practise. You’ll find some simple mouse exercises on the SeniorNet.org website.
To reach them from here, place the cursor over the highlighted ‘simple
mouse exercises’ above – this is known as a ‘link’ – and click the left
button. Did you notice how the cursor turned into a little hand when it
was over the link? That tells you that you can click on that word or
phrase to go somewhere else on that website or on the internet as a
whole.
Step 6: Now try a right-click. Just click the right
button, paying no attention where the cursor is on the screen. A menu
will appear, giving you options. Whenever you right-click, it opens a
menu. If you move your cursor off the menu and left-click, the menu will
close.
