(joke ..) It's easy, just remember to add +1 from "Cmd Shift 3" .. the whole-screen screenshots shortcut. (seriously) Cmd Shift 4 also has AFTERTOUCH - so do the command, draw out the grey capture window, and keep holding the mouse button WHILE trying using different combinations of Ctrl, Option, and Shift. Allows you to resize your capture window. Without the initial SHIFT dumps the file to the Desktop. With the SHIFT adds the screenshot to your clipboard.
