I have a projekt where I have little chunks of animation that I will later have to put together.

Now I´m not sure about the approach. One way I tried was saving the channels in the channel editor with “Export displayed channels as…” but I can´t add one animation after the other. It always overwrites the whole timeline.
how can I asssemble different animations if the channels match?

Also, I found that the rather old pose library is not installed on my computer. I can´t find or open it in the help browser
