title: Editing Code in Zed description: Core code editing features in Zed including multi-cursor, refactoring, code actions, and language server integration.

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
