yugutou You mentioned that the Enter key feels far away when operating with one hand, but the hotkey for mesh tracing can be assigned to any key. I believe this issue can be resolved by assigning the hotkey to a key closer to Enter.
Alternatively, using a separate keyboard for the left hand could also be a solution. In fact, some members of the Spine team use an additional keyboard for their left hand and assign frequently used hotkeys to it. (You can see this in action in the video below.):

I think adding more hotkeys for specific functions is a good idea. However, the OK button appears in various places, and the key assigned to it is consistently Enter. For this reason, I still believe it would be best for users to customize their key assignments accordingly.
I hope this explanation makes sense. Thank you for your feedback!
