Is it possible to copy a dope sheet summary to another project? So I have 2 characters. I made a basic walking cycle animation for the first one and I want to do the same thing for the second character as well. Is it possible do this just by copying the dope sheet?  

My characters are not exactly the same but pretty similar.
If you have saved your animations as Actions (Press the F button to save them), you can then import them into another project by pressing Shift+F1.
