KEY
DESCRIPTION
RETURN
RETURN
(sometimes labeled
ENTER
or with an arrow that curves to the left) is the
carriage return key. Just as you press the carriage return on a typewriter to begin a
new line on the page, a
RETURN
tells the computer you are ending a line of input
and you want to begin a new line.
The computer does not normally process an instruction from you until you press
RETURN
to let it know you are finished with that line.
RUBT

UR
T
RUBT
OU
UR
T
is the deletion key; it backspaces AND deletes. It may be labeled
RUB
or
DEL
.
If you make a mistake while typing an instruction to AMOS, you can erase it using
the
RUBT
OU
UR
T
key.
The
key on most keyboards acts much like the shift key on a typewriter. By
holding down
, you can type upper case letters and the symbols on the upper
half of the keys with two symbols.
CAPS
LOCK
While the CAPS LOCK key is enabled, letters you type appear in upper case. Keys
other than letters are not affected by the CAPS LOCK key on most keyboards.
ESC
This key may be labeled ESCAPE or ALT MODE. It is used with several
application programs (such as AlphaVUE) to signal the end of input, or to switch
between command modes; however, you do not use
ESC
at AMOS command level.
CTRL
Use the
CTRL
(or CONTROL) key with other keys to enter a different kind of
character—a "control character." AMOS and much of the software on the computer
interpret control characters as special instructions.
To type a control character, hold down the
CTRL
key and press the other key. For
example, to type a Control-C, hold down the
CTRL
key and type the letter C. In this
book, we indicate control characters this way:
CTRL
/
C
. Appendix B lists some of
the control characters AMOS recognizes.

Correcting Typing Mistakes
You can correct any mistakes you may make while typing a command line as long as you have not yet
pressed the
RETURN
key. You can:
•
Press
RUBT
OU
UR
T
to erase single characters.
•
Type
CTRL
/
U
to move the cursor to the beginning of the line.
•
Type
CTRL
/
C
to tell AMOS to ignore the line.
