Using the Color Keys
The red, green, yellow, and blue keys
on your BOOKMAN change functions
according to which book is selected.
When the built-in book is selected, the
color keys function as labelled on the
BOOKMAN keyboard. When a book in
a cartridge is selected, the color keys
function as labelled on its cartridge.
Remember, when you have selected
and are using a cartridge book, the
color keys function as labelled on that
cartridge, not as labelled on your
BOOKMAN keyboard.
