Respond to commands

Commands are key combinations that invoke an extension feature. Register commands in the manifest under the "commands" key. For example:

{  "name": "Open developer.chrome.com",  "version": "0.1",  "manifest_version": 3,  "description": "Opens developer.chrome.com when you use Cmd/Ctrl + Shift + Z",  "background": {  "service_worker": "background.js"  },  "commands": {  "open-tab": {  "suggested_key": {  "default": "Ctrl+Shift+Z",  "mac": "Command+Shift+Z"  },  "description": "Open developer.chrome.com"  }  } }

This key combination triggers the commands.onCommand event in the service worker.

chrome.commands.onCommand.addListener((command) => {  if (command !== "open-tab") return;  chrome.tabs.create({ url: "https://developer.chrome.com" }); });
