Select or deselect Options > Link Timeline and
■
Edit Selection.
– or –

■

Link Timeline and Edit Selection enabled
Press Shift+Forward Slash (/) to toggle Link
Timeline and Edit Selection on and off.
If you are working on a film or video scene, you
may want to unlink the Timeline and Edit selec-
tions to find or audition material that is at a dif-
ferent location than the current Timeline selec-
tion. Edit selections can be played (choose Edit >
Selection > Play Edit) without disrupting the
current Timeline selection. Once you find the
material, you can then go back to the Timeline
selection and place it within the context of the
scene.
Figure 11 illustrates another reason you'd want
to unlink the Timeline and Edit selections. In
this example, the Timeline selection sets a range
to be looped on playback, while a MIDI region
(residing within the loop) is selected for editing
purposes. During playback, the Edit selection
can be nudged, quantized, or transposed while
the loop plays back completely independent
and uninterrupted.

While you could theoretically do this with the
Timeline and Edit selections linked, as soon as
playback is stopped, the playback range would
then be updated to that of the more recent edit
range, or to a single note when editing MIDI.
Playback/Edit Markers
Timeline selections are displayed in the Main
Timebase ruler with Playback Markers, which ap-
pear as blue arrows (red when recording). In ad-
dition, there are Pre- and Post-Roll Flags (which
are green when enabled) indicating the location
for pre- and post-roll.
Playback Markers with Pre- and Post-Roll Flags
When the Timeline and Edit selections are un-
linked, Edit selections are displayed in the ruler
with Edit Markers, which appear as black brack-
ets.
Figure 12. Edit Markers
If the Timeline and Edit selections are linked,
Edit selections are represented by the blue Play-
back Markers.
