# Command

> Use Windsurf Command (Cmd/Ctrl+I) for inline code generation and edits with natural language. No premium credits required.

**Command** generates new or edits existing code via natural language inputs, directly in the editor window.

<Tip>Command does NOT consume any premium model credits.</Tip>

To invoke Command, press `⌘+I` on Mac or `Ctrl+I` on Windows/Linux.

You can enter a prompt in natural language and hit the Submit button (or `⌘+⏎`/`Ctrl+⏎`) to forward the instruction to the AI.

If you highlight a section of code before invoking Command, then the AI will edit the selection spanned by the highlighted lines.
Otherwise, it will generate code at your cursor's location.

You can accept, reject, or follow-up a generation by clicking the corresponding code lens above the generated diff,or by using the appropriate shortcuts (`Cmd/Ctrl+Enter`/`Cmd/Ctrl+Delete`)

# Models

Command comes with its own set of models that are optimized for current-file edits.

<Tip> Windsurf Fast is the fastest, most accurate model available.</Tip>

# Terminal Command

You can use Command in the terminal (`Cmd/Ctrl+I`) to generate the proper CLI syntax using prompts in natural language.

# Best Practices

Command is great for file-scoped, in-line changes that you can describe as an instruction in natural language.
Here are some pointers to keep in mind:

* The model that powers Command is larger than the one powering autocomplete.
  It is slower but more capable, and it is trained to be especially good at instruction-following.

* If you highlight a block of code before invoking Command, it will edit the selection. Otherwise, it will do a pure generation.

* Using Command effectively can be an art. Simple prompts like "Fix this" or "Refactor" will likely work
  thanks to Windsurf's context awareness.
  A specific prompt like "Write a function that takes two inputs of type `Diffable` and implements the Myers diff algorithm"
  that contains a clear objective and references to relevant context may help the model even more.
