Operation
Tab/Back Tab - Moves the cursor to the next tab setting.
Modifier Keys
The Shift, Ctrl, and Alt keys are called "modifier keys" because they modify,
or change, the meaning of some other key. The modifier keys are
always
used in conjunction with another key.
They don't do anything when
used alone.
Shift -
There are two Shift keys on the keyboard; a right
Shift key and a left Shift key. Normally, when the Shift
key is pressed, you get capital letters, symbols, and extra
punctuation marks. However, if the Caps Lock key is also
active, pressing the Shift key will generate lowercase letters.
The left and right Shift keys also interact with the Scroll
Lock/Num key to change its meaning from Numeric Mode
(On/Off) to Scroll Lock. The same is true for the Delete/In­
sert key (to be covered later). When the Delete/Insert key
is pressed in conjunction with the right Shift key, it becomes
Insert Mode (On/Off).
Ctrl (Control)
-
This key is used as one of the main
keys for entering programs. Customarily, you press and hold
the Ctrl key, and then press another key. The Ctrl key is
often symbolized by a caret (
�
). For instance, if you see
"' K, you would press and hold the Ctrl key and then the
K
The Ctrl key is also used to modify several of the computer's
keys to activate the meanings printed on the front edges
of those keys. For example, pressing the Ctrl and Scroll
Lock/Num key activates the Pause function for temporarily
freezing the display.
Alt (Alternate) -
The Alternate key is almost identical
in practice to the Ctrl key. It is used in the same way for
entering commands, but it is much less frequently encoun­
tered.
