Premise: The curved arrow on the right side is a “reset” button (which will clear all keyframes and reset the parameter to its default setting). Not shown are left and right facing arrows that appear when the playhead is on either side of a set keyframe which can be used as a shortcut to set the playhead on the next or previous set keyframe. You can have a keyframe set on each frame possible
