Really nice and fast (which is the reason I’m still using Sublime instead of VS Code). I’ve only found one piece of functionality that’s dramatically slow compared to Sublime so far: selecting all of the current highlight. In my current file I have 2,396 occurrences of `<span>`. Selecting all of them in Sublime (with ctrl + cmd + g) is certainly less than 200ms. Doing the same in Zed (with cmd + shift + l) beachballs my machine for around 5 secs.

For most code work that’s probably not a situation to optimise for, but I often work on large markup documents.
