Is there a way to have AE automatically jump to the end of you’re last line to draw the new one?

I’ve been having the same problem. I found a clunky work-around that works ok. I use the hotkeys U and K, in that order, after every stroke. U is the hotkey to make keyframes visible in the timeline, and K is the hotkey to jump to the next visible keyframe. It’s not automatic, but at least you don’t have to pick up your stylus and manually move the cursor after every stroke.
