Don't tell me i have to write a script for this because I just learned scripting to automate some keyframe management and this sounds simple enough.
Though it'd be interesting to do it faster than a binary search?
Or I should probably just rely on the fact that the keyframes are already sorted.
I guess there's also an issue with multiple keyframes beneath the CTI, which one is selected. I might make a specialized one for my current needs for now.
Well, I ended up making a script for it that works pretty darn well. Unfortunately it targets very specifically the "Start" keyframe underneath the first range selector under the first animator under the first textlayer, but that's particular to my needs.
