Countach, Your method is essentially the same as mine. I just don't like having the brown colored squares going across the timeline between keyframes. I often set keyframes on specific attributes that I'm not animating in the timeline simply to use as markers. This is especially true when I'm animating to music, or when I set up several different shots on the same timeline. For that reason, I don't want anything on the timeline that doesn't have to be there. It's just a personal preference. ;-)

Before they made me they broke the mold!
