Where do I download Cursor and which operating systems are supported?

Download from cursor.com — installers for macOS, Windows, and Linux. On first launch, tick "Import VS Code Settings" to inherit your existing VS Code shortcuts, theme, and extensions instead of reconfiguring from scratch.

How do I sign in to Cursor — is a paid plan required?

Sign in with Google or GitHub to get free trial credits — enough to finish the entire Vibe Coding intro track. Pro subscription only matters once you are doing dozens of Cmd+K calls per day. Run the free tier first, upgrade after you are sure it pays back.

Which model does Cursor use by default and when should I switch?

Default is a high-quality model (Claude / GPT-4 tier), right for real code where correctness matters. GPT-3.5 is faster and cheaper, suited for throwaway drafts, naming suggestions, comment translation — anywhere "wrong is fine". Keep the default for daily work; only switch when you hit latency or burn through tokens.

What are the 4 most-used Cursor shortcuts?

(1) Cmd/Ctrl + K — generate or edit code at the cursor, highest frequency; (2) Cmd/Ctrl + L — open the chat sidebar for multi-turn discussion; (3) Cmd/Ctrl + Shift + I — open Composer for cross-file refactors; (4) Cmd/Ctrl + Shift + P — command palette for switching models or toggling features. Build muscle memory for these four first; pick up the rest as you go.

Cursor feels slow on a large project the first time — how to fix?

The index has not finished. Trigger a global search (Cmd/Ctrl + Shift + F with any keyword) right after opening so Cursor indexes the whole workspace; after that Cmd+K and Cmd+L pull context fast. Explicitly adding common folders to the Workspace also stops Cursor from skipping them. The next launch is instant.

Installing Cursor and Basic Setup

Cursor is one of the most popular AI coding IDEs right now. It's built on VS Code with Claude / GPT models baked in. Get the tool installed and memorize the shortcuts — everything after this will go smoother.

Download and Install

Go to the official site: https://cursor.com
Download the version for your OS (macOS / Windows / Linux).
Run the installer. On first launch, you can pick "Import VS Code Settings" to carry over your existing config.

Sign in with Google / GitHub to get trial credits.
Model recommendation: Claude/GPT-4 for highest quality, GPT-3.5 is faster and works fine for drafts.
Stick with defaults for now. Adjust later based on latency and cost.

Essential Shortcuts

Cmd/Ctrl + K: Generate or modify code at the current cursor position (you'll use this the most).
Cmd/Ctrl + L: Open the chat sidebar for multi-turn conversations.
Cmd/Ctrl + Shift + I: Open Composer for cross-file refactoring.
Cmd/Ctrl + Shift + P: Command palette — quickly switch models or toggle features.

Configuration Tips

Turn on "Auto Suggest" in settings for faster completions.
Add your common directories to the Workspace so Cursor can build its index. For large projects, trigger a global search once to warm up the index.
If you're working with a team, set up your Git credentials and make sure git status works properly.

Practice

Create a new file hello.ts, hit Cmd/Ctrl + K and type: "Write a function that prints Hello JR Academy and export it."
Check the generated code, then tweak the prompt to add parameter validation. Notice how fast the feedback loop is.

Cursor 在哪里下载？支持哪些操作系统？

官网 cursor.com，提供 macOS / Windows / Linux 安装包。第一次启动时勾 "Import VS Code Settings" 可以把已有 VS Code 的快捷键 / 主题 / 扩展全部继承过来，不用重新配。

Cursor 怎么登录？是不是要付费才能用？

用 Google 或 GitHub 账号登录就有免费试用额度，够走完整个 Vibe Coding 入门方向。重度使用（每天几十次 Cmd+K）才需要订阅 Pro。先用免费档跑通流程，确认对自己有用再升级。

Cursor 默认用哪个模型？什么时候该手动切换？

默认走 Claude / GPT-4 这类高质量模型，适合需要正确性的真实代码任务。GPT-3.5 速度更快、成本更低，适合写一次性 draft、命名建议、注释翻译这类"错了也无所谓"的场景。日常先保持默认，遇到延迟问题或 token 烧得快再切。

Cursor 最常用的 4 个快捷键是哪些？

(1) Cmd/Ctrl + K — 在光标位置生成或修改代码，最高频；(2) Cmd/Ctrl + L — 打开对话侧栏，适合多轮讨论；(3) Cmd/Ctrl + Shift + I — 打开 Composer，做跨文件 refactor；(4) Cmd/Ctrl + Shift + P — 命令面板，快速切换模型 / 开关功能。先把这 4 个练成肌肉记忆，剩下的后面遇到再学。

大型项目第一次用 Cursor 卡顿怎么办？

是索引还没建好。打开项目后先手动触发一次全局搜索（Cmd/Ctrl + Shift + F 随便搜个关键字），让 Cursor 对整个 workspace 建索引，之后 Cmd+K / Cmd+L 调 context 才会快。把常用目录显式加到 Workspace 也能避免 Cursor 漏扫。索引完成后第二次打开秒开。
