Apple Final Cut Pro 7 - Manual (Page 590)

When video and audio clip items are linked in the Timeline:
• The names of the linked clip items are underlined to indicate that they’re linked.
The underlined clip
name indicates the link
between audio and
video items.
• As long as linked selection is on in the Timeline (the Linked Selection button in the
upper-right corner is green), clicking one clip item selects it and all the items linked to
it.
Click the Linked
Selection button
to turn linked
selection on and off.
When Linked Clips Are Moved out of Sync
When you move clip items in the Timeline, Final Cut Pro checks to see if the relationship
between linked items is still correct. If the relationship does not match, Final Cut Pro
displays out-of-sync indicators in the Timeline. Out-of-sync indicators show the offset
between the linked clip items.
