SUMMARY
Sometimes the Transform effect is not the 1st effect of an effect stack on a clip, if I select this clip and want to jump to the next keyframe of the clip, I 1st have to select the "Transform Effect" in the effect stack and then the shortcuts works. If the "Transform Effect" is the 1st effect in the stack or the only one, the shortcuts for "Next Keyframe" and "Previous Keyframe"  work directly after selecting the clip in the timeline.

STEPS TO REPRODUCE
0. have Shortcuts defined for "Next Keyframe" and "Previous Keyframe" 
1. add more than one clip to timeline
2. add "flip horiz." to one clip as 1st effect in stack
3. add a Transform effect as 2nd effect of this clip in stack
4. select another clip in timeline / switch back to clip with effects and use shortcuts "Next Keyframe" and "Previous Keyframe", until you select "Transform" in the effect stack it should not work because "Flip horiz" is 1st in list


EXPECTED RESULT
* would be nice to have a Shortcut for Transform specific ""Next Keyframe" and "Previous Keyframe""
