Article Jump adds jQuery functionality to a page to scroll from one article to the next via a hotkey. For instance you can scroll down through a stream of node teasers by pressing "j" several times. Then scroll back to the previous article by pressing "k".
The jQuery selector is configurable, so if you have a stream of feed items, you can add a selector of ".content .feed-items" on the module configuration page and users will be able to navigate that stream by pressing "j" and "k" as well.
