# Code editor & LSP

Switch the workspace right pane to **Code** when you want the file tree, editor, and terminal.

## What you get

* **File tree** — open and navigate project files
* **Editor** — Monaco-based editing with save shortcuts
* **Language intelligence (LSP)** — completions, diagnostics, and go-to-definition for common languages via the project sandbox (TypeScript/JavaScript, Python, and others depending on the stack)
* **Terminal** — interactive shell in the private workspace

## When to use Code vs chat

| Prefer chat (Build)               | Prefer Code                         |
| --------------------------------- | ----------------------------------- |
| New features, refactors, installs | Tiny one-line tweaks                |
| Fixing Preview from a description | Reading logs in the terminal        |
| Structural file moves             | Go-to-definition while reading code |

## Tips

* Prefer asking Mythex for large changes so checkpoints stay useful
* After installs, watch the terminal for errors
* Use [Restore](/features/chat) on a checkpoint if an edit goes wrong
