- I key over a button inserts a keyframe. - Alt+I removes a keyframe. - With right mouse button a menu with these options pops up. - Buttons are colored green if the property is animated, yellow if it is on a keyframe. I followed the colors from the UI mockups, but the flicker on keyframes seems too distracting in practice? - This only works for properties on the ID itself at the moment, path callbacks need to be filled in for all structs but mesh still. - It doesn't work when you're over a related label, that needs to be made to work. - I made it insert keyframes outside of any keyingset. Not sure how this is supposed to integrate?
