When editing keyframes in the effects panel, Premiere needs an option to remove all keyframes to the right or to the left of a selected keyframe. Often when editing keyframes, for example, adjusting volume on a piece of music, I might make a cut in a clip that already had keyframes beyond the cut point. Once the clip is cut the keyframes are not visible within the bounds of the clip, which makes it tedious to edit the remaining keyframes. If volume is fading down at the cut point, it will continue fade to the keyframes beyond the bound of the clip, but if I want to change the timing of that fade, I can't see or access the keyframes beyond the bounds of the clip. If I could clear all markers to the right or left, this would allow me to clear out those markers beyond the clips bounds.
