Edit Ranges Mode

Modify Subtree and Modify Child Keys
When working in Dope Sheet, you can turn on or off Modify Subtree and
Modify Child Keys. These let you automatically move the keys for the children,
and/or the tracks for the subtree. If you experience a slowdown while working
with Dope Sheet, try turning these off, and moving the keys manually instead.
Modify Subtree is on by default in Dope Sheet, but off in Curve Editor.
