Ctrl + Tab in Chromium Based Browsers

1. Install the CLUT: Cycle Last Used Tabs extension (e.g. from chrome web store)
2. Go to Manage Extensions page (chrome://extensions/shortcuts)
3. Open console (Right Click -> Inspect -> Tab named "Console")
4. Past this script, and press Enter:

   // Find the id and command for the CLUT extension in this chromium based
   // browser. It will run something like:
   // chrome.developerPrivate.updateExtensionCommand({
   //     extensionId: "cobieddmkhhnbeldhncnfcgcaccmehgn",
   //     commandName: "alt_switch_fast",
   //     keybinding: "Ctrl+Tab"
   // });
   // Inspired by https://fwextensions.github.io/QuicKey/ctrl-tab/ but not
   // using QuicKey as it was not providing the actual seamless switching
   // experience and instead depended on a popup.
   chrome.developerPrivate.getExtensionsInfo().then((extensions) => {
     // Find the CLUT extension by checking its name
     const clutExt = extensions.find(ext => ext.name.includes("CLUT"));
     if (!clutExt) return console.error("CLUT extension not found.");
   
     // Select the command whose description contains "quick"
     const quickCmd = clutExt.commands.find(cmd => 
       cmd.description.toLowerCase().includes("quick")
     );
     if (!quickCmd) return console.error("No command with 'quick' found.");
   
     // Update the extension command using the retrieved values
     chrome.developerPrivate.updateExtensionCommand({
       extensionId: clutExt.id,
       commandName: quickCmd.name,
       keybinding: "Ctrl+Tab"
     });
   });

5. Confirm it worked by looking at shortcuts for CLUT: Cycle Last Used Tabs in the Keyboard Shortcuts tab of the Manage Extensions page: it should say Ctrl + Tab next to the Quick switch option in the list.
