Research direction

Start by reading the virtualized diff rendering and search-related entry points; the issue does not name specific files or tests. Check how the rendered window limits browser search and how large diffs are handled. Done means substring search can find content across the entire diff, including content outside the rendered window.

Description

Prerequisites
Proposal

I'd love to be able to do simple substring search across an entire diff (e.g. in DiffsHub). This would mean a bit of extra UI, and maybe binding to cmd/ctrl+f. I'm not totally sure if there'd need to be any particular affordances made to efficiently search though a large volume of text, but... that seems like it's probably a solved problem at this point in computer science.

Motivation and context

Currently, as scrolling is virtualized, the browser's native page search is only able to find content that's within the rendered window, which for large diffs can be a vanishingly small amount of what's available. GitHub themselves has this implemented for their Actions logs, but it's a pain elsewhere. I usually end up using Zed's git diff view for this, but it doesn't show comments from GitHub, so I end up having to go back and forth and keep scroll position synced manually and it's a whole pain.
