What rhino commands do you use on a regular basis and think others don't know about?

I really enjoyed this wonderful thread, and while reading (and contributing) I realized that it would be a pity to let those tips rot here.
So I decided to go bold and collect a ‘best of’ and put it on Github.
You can see the collection ››› here ‹‹‹.
I want to continously update this site. And while I done it mostly for myself as some kind of Wiki for the Rhino secrets (it’s so easy to forget something…), I hope y’all might enjoy it as well.
