- Add custom docs via @Docs → Add new doc useful for internal APIs.
Example: Hovering over fetch_data() will show its purpose, parameters and usage examples which makes it easier to understand without needing to look up external documentation.
7. Edit and Write Code with Cmd K or Ctl+k
It makes it easy to edit or generate new code using natural language. With just a simple shortcut, we can make changes to our code or add entirely new functions.
How to Use:
- To edit: Select the code, press Cmd + K (or Ctrl + K) and describe the change we need like "Add error handling".
- To generate: Place our cursor, press Cmd + K and provide instructions like "Write a function to sort a list".
Example: Select a function, press Cmd + K, type "Add input validation" and see the changes reflected in the code.
8. Quick Questions
Ask immediate questions about specific code elements without opening the full chat panel. This is great for quick clarifications.
How to Use:
- Select the code we want to inquire about, press Cmd + K (or Ctrl + K) and choose "quick question."
- Ask specific questions like "What does this variable do?" to get instant answers.
Example: Select a variable and ask, “Is this variable used elsewhere?” to get a quick, direct response.
9. Agent Mode
Agent Mode automates end-to-end tasks and allows the AI to integrate with our project to complete coding tasks. This is helpful for handling complex workflows efficiently.
How to Use:
- Enable Composer then access Agent Mode by selecting 'agent' in the settings.
- Provide specific instructions such as "Implement user authentication with JWT" and the AI will generate the code across multiple files.
Example: Provide instructions like 'Create a REST API endpoint' and let the AI generate the necessary code.
10. Multi-File Code Generation with Composer
This feature lets us quickly generate multiple files by describing the structure of the application. It's ideal for projects that involve multiple components and need rapid setup.
How to Use:
- Open the Composer by pressing Ctrl + I (or Cmd + I on macOS).
- Describe the multi-file structure needed for our project like "Create a Node.js project with separate routes, controllers and models".
- The AI will generate the necessary files and code, organizing them within our project.
Example: For a web application, we might generate routes.js, controllers.js and models.js with appropriate boilerplate code to get started quickly.
11. Cursor Debugging
Cursor AI’s debugging tool helps identify and fix errors in our code with ease. It integrates seamlessly into our workflow which provides real-time feedback and suggestions for resolving issues.
How to Use:
- Open the Debug Panel by clicking the debug icon on the sidebar or using the shortcut Ctrl + Shift + D (or Cmd + Shift + D on macOS).
