Commodore Plus 4 - Special keys

SPECIAL RETURN
KEYS
You have to press the return key at the end of each line of
instructions you enter on your Commodore Plus/4 keyboard. You might
think of this key as an ENTER key because RETURN actually enters
information and instructions into the computer.

This key works like the shift key on a regular typewriter. Your Plus/4 has
two SHIFT keys and a shift lock , which works like (he shift
lock on a typewriter.
By pressing the SHIFT key. you can get the graphic symbol on
the right side on each graphics key when you are in upper-case/
graphics mode.
fs
Your Plus/4 is automatically in upper-case/graphics mode when you
turn it on. In upper-case/graphics mode, all the letters appear upper
case without the SHIFT key.
The SHIFT key pressed with a letter key gets upper-case (capital)
letters when you are in upper/lower-case text mode (the same as the
SHIFT key on a typewriter). When in this mode, the letters you type
are ii ower-case except whei /ouusethe shift ke^
NOTE: You can go back and forth between upper-case/graphics
and upper/lower-case text modes by pressing the shift and
key at the same time.
RUN/STOP
Press this key to break into a running program to STOP what your
Plus/4 is doing. When the Plus/4 is running a program, pressing this
key returns control back to you and the keyboard.
When you hold down the shift and RUN/STOP keys simul
taneously,
the Plus/4 loads and runs the first program on a disk in
the disk drive.
