No I mean that in code search you could click "edit" and just change something, which would then post a CL immediately, which you could set to auto-approve, for quick changes.

I believe it was part of cider (the first non-vscode version)

The first version was part of Code Search proper, and wasn't super useful for much more than just typo fixes, since it was essentially just a textarea edit box. That was eventually deprecated and replaced with a button that did the same thing, but opened in Cider instead.
