13## How These Features Work Together
14
15When you're editing code, Zed combines input from multiple sources:
16
171. **Language servers** provide completions, diagnostics, and quick fixes based on your project's types and structure
182. **Edit predictions** suggest multi-character or multi-line changes as you type
193. **Multibuffers** let you apply changes across files in one operation
20
21For example, you might:
22
23- Rename a function using your language server's rename refactor
24- See the results in a multibuffer showing all affected files
25- Use multiple cursors to make additional edits across all locations
26- Get immediate diagnostic feedback if something breaks
