Shamelessly stolen from Wikipedia:
Examples of games that use HJKL are the text-based "graphic" adventures like NetHack, the Rogue series, and Linley's Dungeon Crawl. It is also used by some players of the Dance Dance Revolution clone StepMania, where HJKL corresponds directly to the order of the arrows. Gmail, Google Labs' keyboard shortcuts, and other websites use J and K for "next" and "previous".
