CDO Thank you for explaining your workflow through the video and subtitles!
Regarding the curve distortion visible at 0:39–0:45 in the video, this has been improved in 4.3-beta, so you may want to give it a try.
You can find an overview of this improvement in the following blog post:

As for the issue you mentioned several times about not being able to convert to Bézier curves, this is most likely because the active view was not switched. In fact, the curves for those keys were already set to Bézier, so pressing the Bézier hotkey while the Dopesheet view is active will not change anything. Later, when you clicked on the Graph view, pressing the hotkey caused those keys’ curves to reset to the default Bézier curve. Please note that when the same hotkey is shared across multiple views, its effect will vary depending on which view is active.
Regarding the offsetting of keys, as you showed in the video, it is indeed a task that often requires repeated adjustments. I don’t recall anyone having previously suggested making it possible to adjust the offset without directly selecting the keys, as you proposed, but we have received many requests in the past to improve the efficiency of repeated offset work itself. In fact, the idea for a “non-destructive offset” feature has been on our roadmap for quite some time:

If this feature is implemented, it could significantly change the overall workflow for key offsetting. Nevertheless, I will also discuss within the Spine team the practicality and feasibility of allowing keys to be offset when pressing a specific hotkey, even without directly selecting them.
