Not all keys appearing on timeline; filters don't help


I’m trying to edit some parameters of certain keys…but the only way to do it seems to be from a track view because the keys don’t appear on the timeline.

I have tried every last combination of filters, but MAX seems to have decided that % Along Path keys, for example, don’t get to be on the timeline. I have to go digging through the Track View if I want to edit parameters like Tension or Bias, which is a lot of extra steps for such a simple procedure.

What can I do to make every last key ever appear on the Timeline, and everything in between that and nothing?
Cuz MAX seems to have decided it knows better than I do what I need to accomplish my goals.
