Atari 520ST User Manual

The function keys
are
used
in
software
programs
to perform
specialized procedures. The
[Control] key, like
the
[Shift] and
[Alternate] keys,
is held down
to change the
meaning of
a
character. Refer
to
the manual
for each
software program
to learn
what these keys do.
If
you
have
a graphics printer
attached
to
your ST
Computer,
you
can
print whatever is
on your screen
by pressing the
[Alternate]
and
[Help] keys together.
(Pressing the
[Alternate] and
[Help] keys
again will
stop the printing
process.) This function
is the same
as
using
the Print Screen
option of the
Options menu.
(See
the
section
on Options
in
Chapter
5,
The
Opening Menu.)
