No, I'm not talking about the author of Harry Potter... and I'm actually offended that you even considered this.
I'm talking about the keyboard shortcuts "J" and "K" (amongst others) to scroll/jump up and down in lists.
Using J and K to scroll goes back to the vi editor when you used it on old terminals without cursor keys (or maybe probably earlier, but I know them from vi) ... get the history here.
J/K became really popular with Google Reader (RIP), then later Google+ adopted it, Facebook followed as well, then of course feedly as the Google Reader replacement did it, and now I noticed that flickr (with their infamous redesign) at least adopted J/K navigation.
In case you are not familiar with it... J steps/scrolls down to the next post, K goes one step backward to the previous post.
That simple.
