The example comes from a demo of the Replit AI assistant that does something similar but through autocomplete (https://replit.com/public/images/ghostwriter/demos/creativity/css_complete.mp4). I tried to see if we could have something similar and other helpers.

Also it’s not only about LLMs, you can use this process to sort, dedup or make other operations on your text selection with a shell command which is a nice tool to have.
