Hi ,everyone . Can anyone tell me what this " Toggle selectable" can do ?

I tried both ticking it or not ticking it, but it seems nothing happened.

Thanks in advance !

Right now this only has an effect in virtual reality. If it’s on, you can manipulate it with the controllers, if off, then not. It could be possible to use it for other things. Do you have anything in mind?

Thanks for the reply. but nothing special in my mind.
I am trying to learn more about the slicer, so i can do some simplifications .
Now there are just too many functions which make slicer not so easy to use.
