I installed Zed a few days ago and have been trying to get acquainted myself.

It has far less built-in features for refactoring than other editors you might be coming from. It's handled at the LSP level, get the LSP for your language and hit cmd+ to see what it can do. I'm not working in Python or Rust at the moment (Elixir), but I'm sure they have some good extensions.

I don't get the question. albeit in vim I use just the navigation things and selectors and s/../.. to replace stuff I am probably using something like 1% of it's power.
