copying a key frame from file to file i'm just starting to use blender. I made a rookie mistake and deleted an actor from a file. is there a way to copy the beginning or end key frame from one file to another?
If you have the original somewhere, you can copy it with CTRL+C and then paste it into another Blender instance with CTRL-V.

If you lost the original blend file, you can click on File > Recover Auto Save.
