People with limited motor skills sometimes can't adapt to the keyboard
repeat rate on the Apple IIGS, causing several characters appear after each
keypress.
The keyboard repeat rate can be set from the Control Panel. Here's how to
disable keyboard repeat altogether:
1. In the Control Panel, select the Options menu.
The 'repeat delay' option controls the time between the first keypress
and the time when keys begin auto repeating.
2. To disable the auto repeat feature, move the asterisk all the way to the
left of the sliding scale.
3. To save the changes made to the Control Panel, press Return.
