During the latter-end of 2010, Twitter overhauled their somewhat simplistic website to compete with client-side offerings (e.g. TweetDeck, Seesmic). What I found really impressive was a hidden bit of functionality that allowed the user to navigate around the site using keyboard shortcuts (or hot keys). If you haven't tried it, take a look at the list of shortcuts below and try them out.

Some people I know in the industry think it's a pointless feature. But I believe something so simple automatically enhances the users experience when accessing a site. In fact, you could think of hotkeys as an additional web accessibility requirement for those who don’t have a mouse or just prefer the more direct approach in navigating through a site. Many sites have been utilising hotkeys to get their sites to act like locally installed software programmes, for example Google Docs.

I was very keen on replicating hotkey functionality on my next project. Not surprising, there are a lot of custom jQuery plugins that allowed you to implement some basic keyboard shortcut functionality. The best one I found through trial and error is Mousetrap. I found Mousetrap to be the most flexible plugin to fire your own custom JavaScript events by binding a single, sequence or combination key press.

Using Mousetrap, I could replicate a simple Twitter-style shortcut to take a user back to the homepage by pressing the following keys in sequence: “G H”:

Mousetrap.bind("g h",
    function () { 
        window.location = "/Home.aspx"; 
    }
);
