In the Timeline view, you can easily drag keyframes to change the animation timing, delete them, cycle them and even copy them.
As you animate, you will find that you reuse many positions, drawings, and keys. However, you may only want to paste the drawings or just the keys or maybe everything. There are different paste options available in the Timeline view which give you maximum flexibility when reusing and pasting.
Note that these modes also apply when you drag instead of copying and pasting.
There are three different modes for pasting your selection:
Paste Mode: All Drawing Attributes: Pastes the drawing exposure and keyframes.
Paste Mode: Keyframes Only: Pastes only the keyframes.
Paste Mode: Exposures Only: Pastes only the drawing exposure.
When you have position keyframes set in your drawing layer and you want to move them around when moving your drawing's timing, you can use the Paste Special feature to only move selected keyframes.
You can also use the Paste Cycle and Paste Reverse feature to cycle your selection including keyframes and drawings.
If you want to cycle a portion of your animation, you can use the Paste Cycle command. You can also use the Paste Reverse command to completely reverse the flow of your animation.
