google reader keyboard shortcuts

speaking to a unix-consultant at work yesterday, he told me that I had to use the old vi keyboard shortcuts to navigate in a console menusystem.
i told him that it was no problem and that i have owned oreilly's learning the vi editor for eight years.

but then i struck me.
i use the google reader shortcuts a lot and the shortcuts for "up" and "down" is the same as for vi!

"k" for up and "j" for down.
