I've been putting together a small app that writes settings to the registry. Half way through coding this I thought "Hang on! I know I've written something similar to this before...".

I open the MSN Deskbar, enter the name of the function and it shows me exactly the .cs file where I did indeed write this before. Cool! Same goes for XML files, config files etc.

Now, what would be really neat would be take that search, run it as a VS.NET add-in with the ability to extract the function into my new code.  Re-use at it's finest <g>
