In reply to Ian Dunn.

Ian, this is a very cool plugin! Thanks for making it. I think the difference between the two can be boiled down to power-user or not. If you compare your plugins functionality to the spotlight on mac, even though it's really great and easy to use, some people never use it.

Also, you could include a small hint somewhere that reinforms user of the keyboard shortcut. I think there's a possibility that people forget over time or don't even know that somebody else installed your plugin on the site. My preferred location would be in the wp-admin-bar-site-name dropdown.

I also left you a review on your plugin site. Cheers.
