Step-by-Step Instructions

Launch Cursor IDE

Open Cursor IDE from your applications folder or desktop shortcut. Ensure you're logged into your Cursor account to access AI features like Composer.

If you haven't logged in yet, you'll see a login prompt in the bottom status bar

Use keyboard shortcut method

Press Ctrl+I on Windows/Linux or Cmd+I on Mac to instantly open the Composer panel. This is the fastest way to access Composer from anywhere in the editor.

The keyboard shortcut works even when you have files open and are actively coding

Access via sidebar icon

Look for the Composer icon (chat bubble with sparkles) in the left sidebar panel. Click on it to open the Composer interface in a dedicated panel.

The Composer icon may be located near the bottom of the sidebar icons

Use command palette method

Press Ctrl+Shift+P (or Cmd+Shift+P on Mac) to open the command palette. Type composer and select Open Composer from the dropdown list.

You can also search for 'AI' in the command palette to see all AI-related commands

Access through menu bar

Navigate to the View menu in the top menu bar, then look for Composer or AI Tools submenu. Click on Open Composer to launch the feature.

Menu locations may vary slightly between different versions of Cursor

Verify Composer is active

Once opened, you should see the Composer panel with a text input field and AI chat interface. The panel title should show Composer and you'll see a prompt asking what you'd like to build or modify.

If the panel appears grayed out, check your internet connection and account status

Start using Composer

Type your code request or question in the input field at the bottom of the Composer panel. You can ask it to generate new code, explain existing code, or make modifications to selected text.

Select code in your editor before opening Composer to give it context about what you're working on
