To delete all keyframes of one layer property:
Click the stopwatch icon to the left of the name of the layer property to deactivate it.
Note: When you deselect the stopwatch icon, keyframes for that property are permanently
removed and the value of that property becomes the value at the current time. You cannot
restore deleted keyframes by reselecting the stopwatch. If you accidentally delete
keyframes, choose Edit > Undo.
Moving and copying keyframes
You can easily move keyframes to different points in time or copy them to different layers.
Moving keyframes makes it easy to change when animations occur. Copying keyframes
makes it easy to use the same property setting in different layers. You can also copy a
property value from a layer that contains no keyframes. For more information, see
"Copying a value from a layer without keyframes" on page 102.
Note: To copy an entire layer, including the source footage and keyframes, see "Dupli-
cating a layer" on page 74.
Moving keyframes
You can move any keyframe to a different point in time. When you move keyframes, you
move the values and settings they contain.
To move a keyframe to another time:
Drag one keyframe icon to the desired time.
To move multiple keyframes to another time:
1 Select the keyframes you want to move. See "Navigating and selecting keyframes" on
page 99.
2 Drag any selected keyframe icon to the desired time. All of the other selected
keyframes maintain their relative distance from the keyframe you drag.
To expand or contract a group of keyframes:
1 Select at least three keyframes. See "Navigating and selecting keyframes" on page 99.
2 Hold down Alt (Windows) or Option (Mac OS) and drag the first or last selected
keyframe to the desired time.
To move a keyframe precisely to a different time:
1 Move the current-time marker to the desired time.
2 Hold down Shift after you begin to drag a keyframe icon to the current-time marker.
When you drag over the current-time marker, the keyframe snaps to the current-time
marker.
Copying and pasting keyframes
To use the same keyframe values at another point in time or in another layer, copy and
paste them. You can copy keyframes between layers for the same property (such as
Position) or between different properties that use the same type of data. The keyframe
properties you can copy between include the following:
