I recently found out about keyboard shortcuts, they're truly awesome!
One place I often visit, but has no shortcut yet, is the review menu. I'd suggest adding this by pressing g (go to...)
+ r (review)
. I bet the few clicks it saves us really adds up over time.
Edit:
After hitting 2k rep on SO, I am reviewing a lot more than before, as I'm going for the Copy Editor badge.
This shortcut would definitely improve the experience for myself & other reviewers.
2nd Bounty:
After getting the Copy Editor badge, this is still a much needed feature. Let us tweak 'em keyboard shortcuts!
