Why does selecting an object now suddenly slect the whole timeline?

[Ken5CB5]

I'm sure I could previously select a single frame by clicking the object in the main window, but now it selects the entire time span in the timeline, what invisible toggle have I triggered?

Figured it out; it was auto keyframe that was turned off.

As soon as I saw this I was going to say turn auto keyframe off. lol Good job.
