[Feature Request] Press delete keyboard to clear annotation

[z1ying]

What feature or change would you like to see made?

Hi, I am using measurement tools, like height, length, and angle. Now I hope it can be cleared when I press Delete keyboard because it is easier to interact. I know you provide eraser tool to delete annotation. But I still want to try a new way to clear current annotation that is green. Can you give me an instruction to how to implement it?

Why should we prioritize this feature?

Because it is more convenient to use when I want to delete the annotation.
