Where’s That fnSwitch? For all of you PowerBook and iBook users, your function keys (F1-12) may be reserved
for settings such as screen brightness, volume control, and keyboard backlight. This
default system behavior may interfere with any Avid commands you may want to map
to these keys, because you have to hold the fn key for them to work properly. No longer,
if you install a free third-party product called fnSwitch.
