I don't know about that, but you do need to at least interact with the code on some level, eg. by cut+pasting, then playing around with the code to make it do different things.

Also, I don't know many professional programmers who type everything in by hand. It'll be something copied from a previous project, or cribbed from the documentation / somewhere online, then hacked into shape.

Of course, in order to do any of that you need to understand what's going on, but there might be easier ways to do that than manually typing in code.
