Key Function
F1 request help
F2 remove or restore the control area
F3 call up the commands for selection
The remaining two function keys are used for actions particular to each program.
HELP
The first option displayed at the top left of the control area, indicates that help is available
by pressing F1.
When you ask for HELP there will be a short pause before the display changes to show
the Help information.
Help will suggest other topics for which help is available. Type the name of the topic and
press ENTER. You do not need to type in the whole name, just enough characters for
it to be distinguished from the other topics. You can repeat this as many times as
necessary.
Pressing ENTER without selecting a topic will take you out to the previous level. ESC will
take you right out of HELP and back into the program.
Help is always available, provided that the program cartridge is in Microdrive 1. Press F1
and the most appropriate Help information will be displayed.
THE LINE EDITOR
You can use the line editor to change or correct a line of text that you have typed in. All the
QL programs use the same line editor, but each program uses it in a way most suitable for
that application In QL Quill you use the line editor, for example, for editing the text in
commands and QL Archive uses the editor extensively for editing database programs.
The line editor uses the four cursor keys, together with the CTRL and SHIFT keys.
