Using the Keyboard
Other Keyboard Features
The UNIX PC keyboard has some additional special
features:
o Many keys repeat when held down continuously,
as does the space bar on an electric
typewriter.
o Two keys, the Caps Lock and Num Lock keys,
have lights that indicate when the key is in
effect.
When you press the Caps Lock key once, the
light comes on to remind you that the letter
keys will now produce capital letters without
using the Shift key. Press the Caps Lock key
again, turning off the light, and the letter
keys produce lowercase letters.
Similarly, pressing the Num Lock key so that
the light turns on makes the keys on the
lower-right side of the keyboard type
numbers. Press the Num Lock key again and
these keys return to their usual functions.
o The Ctrl key is similar to the Shift key in
that you hold the Ctrl key down while typing
other keys. The instructions for the
software you are using will tell you when to
use the Ctrl key.
o The F2 key is marked Call to indicate that
holding down the Shift key and pressing the
F2 key opens Telephone Manager. This action
is described in the AT&T
UNIX
PC Telephone
Manager User's Guide in the Communications
Management binder.
o Many keys have two labels, one at the top and
one at the bottom. This labeling means the
top function is performed when you press the
key with the Shift key held down, and the
bottom function is performed when you press
the key by itself.
