All the relevant layers

Is there a way to tell Moho "Show me all the layers that have any animation in them in the Timeline, and don't show me any that don't"? When I realize way late that there needs to be 1.4 seconds more before X thing happens, and X thing involves animation of a zillion layers, it would be nice to not have to try and remember everything that moves.

I know it's possible to select all keyframes, but I would want to select all keyframes after the current time. If I could do that I could then slide them over.

Have you tried Animation > Rescale Keyframes. Can be used to shift, shrink or stretch parts or all of the animation.

I know about that, but actually use alt-drag more frequently. I was hoping there was something more elegant. What I’d really like is just to be able to see every layer with a key frame in it anywhere in the project, so I have a clearer idea of what I’ve got.

The AE KeyTools script has an option to Show All Layers with KeyFrames (set timeline visibility) .

Not sure if I'm reading your request properly but perhaps Nudge Keys tool is what you're looking for
