As a devoted Google Reader user, I relish any tips I can use to make it even more useful — so imagine my delight the other day when I let my laptop slip (I told you I was a klutz) and grabbed for it, panicked — and accidentally had hit a key combo that brought up a key of Google Reader keyboard shortcuts.
Don't worry, I replicated it — it's shift + ? — and you can also open it as a separate page.
All this time I've only known about J and K to go up and down through stories, but there's a whole world of keyboard shortcuts! Somehow these always end up being faster than using my mouse for me — not unlike my other new beloved shortcut to shut down my Mac!
