If you have some curves selected in the timeline window and attempt to use the SHIFT+, or SHIFT+. shortcuts, they won't work. This is inconsistent with other shortcuts like CTRL+, and CTRL+. which do work while curves are selected.

1. Open the attached project and open Timeline.scene
2. Open the timeline window and select TimelineContainer from the scene hierarchy
3. Expand the clips on the timeline to show the curves
4. Select a curve
5. Attempt to use the SHIFT+, or SHIFT+. shortcuts to skip to the beginning/end of the timeline
6. Shortcuts don't work
