You asked about a "screen scrape." I can think of 2 ways.
Command-shift-3 takes a picture of the whole screen (similar to Print Screen in Windows).
Command-shift-4 turns your cursor into crosshairs. You then drag from start location to end location; it takes a picture of anything within the field you created. (Similar to Alt-Print-Screen, except it's not based on a focused window, but rather the exact coordinates you would like).
As my opinion only, Mac's ability to take screenshots has always surpassed Windows. I hate that I have to actually paste my shot somewhere after hitting Print Screen in Windows. At least in OS X, it leaves the PDF file on my desktop. I can do whatever I want with it, whenever I want to do it.
