# Command K

## FEATURES

### Command K

Command K lets you edit and write code with the AI. To edit, try selecting some code, click "Edit," and describe how the code should be changed. To generate completely new code, just type Command K without selecting anything.

**Tip:** Editing with Command K works best with selections between 1 and 50 lines. Edits also see the lint errors in your selection, so you can say "fix."
