280 Chapter 13 Managing Corrections and Grades
To collapse or expand a group:
m Double-click any group’s node.
When a group is collapsed, the shots that are connected to that group are hidden.
Double-clicking a collapsed group makes all the hidden shots visible again.
Once you’ve created a group, copying a correction or grade to the group is easy.
To copy a grade to a group:
m Drag a grade bar from the Timeline onto any group node.
The grade you dragged overwrites the currently selected grade of every shot in that
group. Unselected grades are not affected.
You can also copy a correction from one particular room to the same room of the other
shots in a group.
