The Quick Tabs extension for Google Chrome lets you hit a single hotkey to pop up a list of all your tabs, and you can use the keyboard to quickly narrow down to the tab you’re looking for. If you frequently use loads of tabs, this could be a great extension for you.

It’s inspired by the search and switch functionality in many programming editors, and it really works well. Hit the Ctrl+M shortcut key, which is configurable in the settings, and then start typing. Hit enter to flip to the tab you want. Note that you’ll need to restart all your Chrome tabs before it’ll work.

Thanks to @cbeust for pointing this one out.
