Small things - Select Rectangle of Text

I found something really small and simple, but it's changed my world (ok, slight hyperbole). While most C# developers already know about it, for some reason I'd never come across it.

It's possible to select a rectangle of text with Visual Studio. And all you have to do is hold down alt while you're holding down the left mouse button. Easy peasy! This is especially handy when you're using something like Specflow and you have tables of data you're updating. Give it a go, it's awesome.
