yugutou Thank you for reporting the issue! I have confirmed that we can reproduce this issue and have created an issue ticket to fix it: EsotericSoftware/spine-editor879

另外能否给描绘完之后的【确定】也添加一个快捷键

Indeed, since pressing Enter is treated as pressing OK in the Rename <Item> and Split windows, I think pressing Enter should be treated the same as pressing OK when tracing the mesh. I have created an issue for the improvement here: EsotericSoftware/spine-editor880

yugutou Thank you for using 4.3.08 so soon!

I suppose it is possible to create a hotkey for this purpose, but from the perspective of consistency with the behavior of other windows, I think it would be odd to create a hotkey for confirmation just for tracing.

I think this is something that should be solved by user ingenuity rather than the editor feature. For example, before sequences were available, Erika used AutoHotkey to create a script for easily switching between frame animations:

A similar script could still be set up today to automate consecutive hotkey inputs. (The OK button for tracing remains disabled until tracing is complete, so scripting it may take a bit more effort.)

Ideally, I believe a dedicated function for mass mesh tracing should be added rather than relying on a hotkey-based solution. (Just to clarify, multiple mesh tracing is also on our roadmap!: EsotericSoftware/spine-editor852 )

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!
