A few problems Rated 4 out of 5 stars
It's okay, but doesn't work for rich text editors or forms... Only text area's, which kinda sucks. What's more, I'm not sure but I don't think it let's you use 2 keys as a shortcut (I just use TAB, anyway), and it could be made better in numerous ways.
It's pretty helpful at times though. I just wish more people made things like this as it's the only addon that does this.
