Apple Final Cut Express HD - Manual (Page 372)

372 Part VI Rough Editing
To enable Auto Select on one track while simultaneously disabling Auto Select on all
other tracks:
m Option-click the Auto Select control on the track you want single out for Auto Select. (If
Auto Select is off for all tracks, you need to Option-click the control twice.)
If you Option-click the Auto Select control on a video track, Auto Select is disabled on
all other video tracks in the sequence. If you Option-click the Auto Select control on an
audio track, Auto Select is disabled on all other audio tracks in the sequence. Option-
clicking allows you to quickly target a single track for editing operations.
To explicitly select a region between Timeline In and Out points:
1 Enable the Auto Select controls for tracks you want to select from, and disable the Auto
Select controls for tracks you want to exclude from your selection.
2 Set In and Out points in the Timeline.
3 Choose Mark > In to Out (or press Option-A).
The region of clips between the In and Out points on tracks with Auto Select enabled
is selected.
In some instances, the Auto Select controls are ignored:
 If no Auto Select controls are enabled, nothing in the Timeline is automatically
highlighted, and only selected clips will be operated upon (just as in earlier versions
of Final Cut Express HD).
 If you use the Selection, Range Selection, or Edit Selection tool to select clips in the
Timeline, these selections are prioritized over the region between sequence In and
Out points on tracks with Auto Select enabled.
 If you use a command that only applies to the topmost visible video clip item (such as
when performing match frame operations), the clip item seen in the Canvas is
affected by your command, not the clip on the lowest-numbered track with Auto
Select enabled.
Option-click the control
for the track you want
to single out for
Auto Select.
