I understand Mac OS X comes with a built-in screen capture. I forgot the function, but I think it's CTRL + one of the F keys. I have only played around with it once and from memory, it took only a photo of my entire screen. I need something a little more refined.... I need a program where I can capture a specific area of something I am working on within my desktop. Perhaps a photo image, perhaps a portion of a webpage or just a picture of something happening somewhere on my screen. Windows had a great program called SNAGIT that I was able to map out exactly what elements of my desktop I wanted captured. What program does this for the Mac? Thanks in advance!
