Commodore VIC-20 - THE KEYBOARD

Chapter 1: Introducing the VIC 20 Computer 7
THE KEYBOARD
In almost every application the keyboard is used to communicate with
the VIC
20. The keys are arranged much like those on a standard typewriter.
Unlike typewriter keys, however, the VIC 20's keys
can be used to access as
many as three
or four different symbols, characters, or functions.
The keys on the VIC
20 may be classified by function as follows:
• Alphabetic keys
• Numeric keys
Special symbol keys
· Graphic keys
· Function keys
• Cursor control keys
Alphabetic Keys
The alphabetic keys include the 26 letters of the alphabet in both upper
and lower case. When the VIC 20 is powered up, letters are displayed in
upper-case.
To display lower-case letters, press the COMMODORE and
SHIFT keys simultaneously. If you are typing lower-case letters and wish to
insert
an occasional upper-case letter, use the SHIFT key as you would on a
typewriter. Press
SH,IFT-COMMODORE again to return to upper-case mode.
