I have a problem with Animation Timeline. I watched this video: http://www.youtube.com/watch?v=xXsBrNdN5cI
All is ok, but with giving arrows (or black points - I think it are keyframes) on the blue animation timeline, I have a problem. I don't know how to denote keyframes. With mouse it doesn't go. I tried maybe all keys, but nothing doesn't give me there black arrows on the timeline.
Have a nice day!
