Even though I've heard that E is the most commonally used letter in the English language, I'd say that the letter J might be the key that is used most often on my keyboard, and that has to do with the fact that it is the shortcut for Google Reader that allows you to quickly jump to the next post.
I check the RSS Feeds that I subscribe to a couple of times a day, and using the J key (and occasionally the K key to backtrack when I go too fast) I can get through a hundred of feeds in a couple of minutes as I scan the headlines and text for something that interests me.
The other day, as I was looking actually visiting a blog, I automatically went for the J key to scan to the next post. It obviously didn't work, but it gave me an idea:
How neat would it be if there was a browswer plugin that would allow you to quickly navigate a blog or website using only a few keys in much the same way Google Reader works? I imagine the pluggin as working so that it would automatically recognize a Headline or new section and jump to it.
On a blog, it would work relatively easily. On a site with a more complex website, I think it could work as well. Rather than scrolling all over the place though, it would just move onto the next section and highlight it for you.
What do you think? Does this idea have merit?
