Display or edit source files using the Quick source tool
Use the Quick source tool to display or edit source files when using a tool other than the Sources tool.
The main place to view source files in the DevTools is within the Sources tool. But sometimes you need to access other tools, such as Elements or Console, while viewing or editing your source files. Use the Quick source tool, which by default opens in the Quick View panel at the bottom of DevTools.
