Okay, I got it for you :))))
And I think the extension is quite good.
It's called Sexy Undo Chrome Tab, and you can open a tab with Control Z. 🙂
You have to get the extension in the Chrome Store. So first you need the Opera extension, "Download Chrome Extension." https://addons.opera.com/en/extensions/details/download-chrome-extension-9/?display=en
With that extension, you can go to the Chrome Store shopping. Now in case you haven't gotten a Chrome extension yet: After you download the extension, Sexy Undo Closed Tab, you have to click on the Opera 20 menu, click on extensions, and then find Sexy Undo Chrome Tab. Click on install. You'll see then on your toolbar the icon for it. Right click on it,then click on options, and make sure you have a check in the box, Enable Control Z shortcut. I tried it out and it works. You can also get a running count of the number of your closed tabs, can open any of them via mouse, and more.
