Yep, using macros are the way to go for a task like this one. I'd use 'A' here to jump into the insert mode at the end of line though (commenting because '$i' part made me realize that I had probably never used '$' for movement at all).

That's a good point, '$i' starts inserting just before the last character, whereas with 'A' you'd save the '$i' but have to delete the quote. One cat with many ways to skin it!
