Editing Code

Zed provides tools to help you write and modify code efficiently. This section covers the core editing features that work alongside your language server.

What’s in This Section

• Code Completions — Autocomplete from language servers and AI-powered edit predictions
• Snippets — Insert reusable code templates with tab stops
• Formatting & Linting — Configure automatic code formatting and linter integration
• Diagnostics & Quick Fixes — View errors, warnings, and apply fixes from your language server
• Multibuffers — Edit multiple files simultaneously with multiple cursors

How These Features Work Together

When you’re editing code, Zed combines input from multiple sources:

1. Language servers provide completions, diagnostics, and quick fixes based on your project’s types and structure
2. Edit predictions suggest multi-character or multi-line changes as you type
3. Multibuffers let you apply changes across files in one operation

For example, you might:

• Rename a function using your language server’s rename refactor
• See the results in a multibuffer showing all affected files
• Use multiple cursors to make additional edits across all locations
• Get immediate diagnostic feedback if something breaks
