Figure 1-5: A sample computer keyboard
On some keyboards, the navigation keys aren’t separate; they are combined
with the keys on the numeric keypad. In that case, use the Num Lock key on
the keyboard to decide which keys you want to use. When the Num Lock key
is On, the numeric keypad acts just like an adding machine’s keypad. When the
Num Lock key is Off, the navigation keys take over, and the numeric keypad no
longer types numbers.
Function Keys
The keys labeled F1, F2, F3, and so forth on your keyboard are called function
keys. The F1 key is the Help key — you can press that key at any time for help.
The exact purposes of the remaining function keys depend on what program
you happen to be using.
The Windows and Application Keys
Some computer keyboards have a couple of extra keys specifically designed
for Windows. One, named the Windows key, shows the flying window logo
as shown at top left. If your keyboard has that key, you’ll most likely find it
between the Alt and Ctrl keys on your keyboard. If your keyboard has an
Application key, shown at bottom left, that one will likely be near one of the
Windows keys on your keyboard.
The Windows and Application keys are entirely optional, so don’t fret if your
keyboard doesn’t have them. Anything you can do with one of those keys, you
can also do with the mouse or even some other keys. For example, if you have
a Windows key on your keyboard, you can tap it to make the Start menu appear.
Whether you have a Windows key or not, you can also make the Start menu
appear by clicking the Start button or by pressing Ctrl+Esc. Which brings us to
that little plus sign. . .
