Jarvis is your administration assistant, putting WordPress at your fingertips via a launchbar interface.
Think of Jarvis as a content management launch bar. Once Jarvis is installed all you have to do to start using it is hit the quick key "/", type in your search (eg, "settings") and select the page you're looking for. It's the fastest way to get from the dashboard to editing your anything on the admin side.
Permalinks+ enter and you're there.
Contact+ enter and you're there.
Nigeria Caving+ enter and you're there.
The idea is to make it easier for anyone using the admin side of WordPress to get to the pages they're looking for.
