 7. While Inline suggestions are great at suggesting code similar to an autocomplete mechanism, Next Edit Suggestions (NES) predict the next logical change in your code based on recent edits anywhere in your file.

It can track recent changes to anticipate future edits, working across multiple lines and symbols. It will highlight suggestions with arrows in the editor gutter.
