Command palette for Chrome.
Commander is a command palette for Chrome. You can perform all actions that you would using a mouse or keyboard shortcuts that are impossible to remember. You never have to use the mouse anymore - just use Commander. No more complicated keyboard shortcuts. Just one to open Commander.
Now you can search Wikipedia, YouTube, IMDB, and Dictionary.com directly from Commander. You can also add custom actions (only for advanced users) - just click the options link in the extensions page!
Install, hit Ctrl+Y or Cmd+J and you're good to go!
