How to delete all animation from an appended file? So, I have appended a file to a blender scene, and now I want to delete all the animation from the previous appended scene. I have tried going into the dope sheet, selecting all keyframes with A and hitting X, but to no avail. Any tips/is this possible?
Is is possible the channels are locked / protected?

You can click the lock icon to toggle this, or press Tab while your cursor is hovering over the channel.
