Press SHIFT and REVERSE simultaneously to make future transitions
auto-reverse. The arrow below the highlighted effect on the PREVIEW screen
becomes an auto-reverse arrow to show that auto-reverse is set. The auto-
reverse arrow points forward or reverse to show the direction that will be
used for the next transition.
While auto-reverse is set, you can manually switch directions using the
REVERSE key.
Auto-reverse remains set until you press SHIFT and REVERSE again to go
back to one-way transitions. The direction and auto-reverse settings remain
in force as you change transition effects.
