It is quite often that I'll find myself wanting to duplicate a whole bunch of text, or wanting to copy and paste a vertical "column" of code. You can do this by holding down the ALT key while selecting/dragging your cursor, or you can hold ALT and SHIFT and use the arrow keys to create your selection. I know this is kind of hard to understand just what exactly column select does for you, so I created a 20 second screencast.
Just know that I start off by holding ALT then dragging down, then I start typing "list.Add...". Once I'm done, I select the "column" of "1"s and paste them in the first name field. These same shortcuts even work in
Notepad++!
