ButterKnife is a Visual Studio Add-In that allows you to search for a string in n number of databases and/or your solution. You can double-click an item in the result set and it will open a window with the code in it. You can also right-click on the output and copy it into the clipboard in tab-delimited format so that you can paste it into an Excel spreadsheet for further analysis.  Don't give me sh*t about how poorly written it is (Justin/Oskar) because it's highly useful.  I started working on this years ago, but only got it to a decent point within the last year.
