How to erase, delete or reset one single shape in jit.gl.sketch?

Gary Leyrn's icon

Hello,

Some help, please. I need to know which command can I use to erase one single drawn shape in jit.gl.sketch. For example, let's say, in the attached patch, I only want to delete the sphere, but not the line.

Please, any ideas about how to do it?
Thank you. in Advance.
