 8Use this section to run and test code in Zed, then debug issues without
 9leaving the editor.

11## What's here
12
13- **[Terminal](./terminal.md)**: Zed's built-in terminal emulator. Open multiple terminals, customize your shell, and integrate with the editor. Tasks and commands run here.
14
15- **[Tasks](./tasks.md)**: Define and run shell commands with access to editor context like the current file, selection, or symbol. Use tasks to build, lint, run scripts, or execute any repeatable workflow.
16
17- **[Debugger](./debugger.md)**: Set breakpoints, step through code, and inspect variables using Zed's built-in debugger. Works with C, C++, Go, JavaScript, Python, Rust, TypeScript, and more through the Debug Adapter Protocol.
18
19- **[REPL](./repl.md)**: Run code interactively using Jupyter kernels. Execute selections or cells and see results inline—useful for Python, TypeScript (Deno), R, Julia, and other supported languages.
