It&#x27;s a good point that a lot of editor latency issues aren&#x27;t specific to typing. One thing that has always annoyed me is if an editor has slow find-and-replace for large files or projects.<p>I also find it interesting that you claim that humans don&#x27;t notice latency under 100ms as though it is established fact, considering the OP spends basically the whole first section trying to debunk that incorrect but commonly quoted belief.
