Basically I need a one click solution to the screen capture program built into OS X. I want something that I can pin to the dock and when I click it it performs the command+shift+3 that copies the whole screen and saves a png to the desktop. I have found some commands to call up key codes for the letter keys but I need to know how to call up the other keys. Would it be easier to just make a script in the script editor. I'm not a mac / unix guy and I realize that this is really simple I'm just new at it. Anyway help would be awesome.
