finding keyframes

Unlike Bryce, when you reopen an animation project the timeline doesn't display the keyframes that were set prior. I at least don't see them anymore. How do you find all the keyframes that were placed beforehand! There were little tags or marks but they no longer display.

I am seeing the keyframe markers - do you have an item with keys selected? Is your animation keyed, or does it use an AniBlock?
Thanks for the reply and we're all set, with this anway.
