# Diff opened tabs

Here are the quickest ways to diff two open tabs in VS Code:

**1. Command Palette (fastest)**

1. Focus the first tab.
2. Press `Cmd+Shift+P` and run **File: Compare Active File With...**
3. Pick the second file from the list; open editors appear at the top.

**2. Open Editors panel (works for unsaved/untitled tabs too)**

1. In the Explorer sidebar, expand **Open Editors**. If it's hidden, enable it from the `...` menu at the top of Explorer.
2. Right-click the first tab and choose **Select for Compare**.
3. Right-click the second tab and choose **Compare with Selected**.

**3. Explorer multi-select (for saved files)**  
`Cmd+click` both files in the file tree, then right-click and choose **Compare Selected**.
