Cursor Tutorial

Step 1: Download, Install, and Open Your First Project

First, go to cursor.sh and click the big 'Download' button. I tested this on Mac and Windows; the installation is as straightforward as any other app. Once installed, open Cursor. You'll see a familiar VS Code-like interface, but with a crucial AI sidebar on the right. Don't just open an empty window. The most important action is to open an existing project folder. Click 'File' > 'Open Folder' and select a directory with some code in it—even a simple 'hello world' script works. This gives the AI the essential context it needs. What surprised me was how instantly it began indexing; you'll see a small loading indicator in the status bar. Wait for this to finish before proceeding.

Step 2: Master the AI Chat Interface and Ask Your First Question

Locate the AI Chat panel, usually on the right side. Click the text box at the bottom that says 'Ask anything about this codebase.' This is your gateway. In my experience, starting with a specific, file-focused question yields the best results. For example, open a file in your project, then in the chat, type: 'Explain what the `calculateTotal` function in `utils.js` does.' Hit Enter. Cursor will read the entire file and the relevant function, then provide a concise, accurate explanation in plain English. What I love is that it often references other related files, showing its deep comprehension. You can also @-mention specific files in your question to direct its attention precisely.

Step 3: Generate Code with the Magical Cmd+K (Ctrl+K) Shortcut

This is Cursor's killer feature. Place your text cursor anywhere in your code editor—even on a blank line. Now press Cmd+K (on Mac) or Ctrl+K (on Windows/Linux). A small command box appears. Here, you tell the AI what to write. Don't be vague. Instead of 'write a function,' try: 'Write a Python function that takes a list of integers and returns a new list with only the even numbers, using a list comprehension.' Press Enter. Cursor will generate the code block directly into your editor. You can accept it, discard it, or, crucially, use the 'Chat' button on the generated block to ask for revisions. I use this dozens of times daily for boilerplate, tests, and simple utilities.

Step 4: Perform Intelligent Edits and Refactors

Beyond writing new code, Cursor excels at editing existing code. Select a block of code you want to change. Right-click and choose 'Cursor: Edit with Instructions' or use the shortcut Cmd/Ctrl + L. A command box appears. Give an instruction like: 'Refactor this function to be asynchronous,' or 'Add error handling to this API call,' or even 'Simplify this complex conditional logic.' Cursor will analyze the selected code and your entire project's context to produce a coherent edit. What surprised me was its ability to make changes across multiple files if your edit logically requires it—like updating a function signature and all its callers. Always review the diff it shows before accepting.

Step 5: Manage AI Context and Model Settings for Best Results

Cursor's power comes from its context window—the amount of your code it can 'see' at once. By default, it uses a smart selection. You can manage this. Click the Cursor agent icon in the status bar (bottom left). Here, you can see which files are in the 'Current Context.' You can manually add files to ensure the AI considers them. For complex questions, I often manually add the project's `README.md` and key configuration files. Also, click on 'Settings' > 'Cursor' to choose your AI model. The free plan uses a limited model. The Pro plan unlocks Claude 3.5 Sonnet and GPT-4, which I've found significantly better for complex reasoning. Adjust these settings based on your task's complexity.

Step 6: Integrate into Your Daily Workflow and Learn Keyboard Shortcuts

To move from testing to daily use, you must integrate it. My stance is clear: use Cursor as your primary editor for all new work. Start your day by opening your project in Cursor, not VS Code. Use chat for debugging: paste an error message and ask 'What does this error mean and how do I fix it in my code?' Use Cmd+K for all new code stubs. The key to speed is mastering shortcuts: Cmd/Ctrl+I to open the quick chat, Cmd+K for generate, Cmd/Ctrl+L for edit. I was skeptical about leaving my old editor, but after a week of forcing myself, the 10x boost in writing mundane code and understanding legacy codebases made me a convert. It's not just an add-on; it's a new way to think.
