Yeah but being able to drag a selection beats out Windows by a lot.

I always reverse the shortcuts to that copy is: command + shift + (3/4) and save file is command + shift + control + (3/4)

Some other os x screenshot tips:

- hold space while dragging a selection and you can reposition the selection's origin

- press space to switch to window capture mode. This captures the whole window even if it is obscured.

Fun fact up until recently (mountain lion I believe) the capture window icon was a holdover from NeXT. I wish they'd left it alone, the new one isn't nearly as cool :)

Feel free to change them in System Preferences to your own liking.

I don't think that you need `Control`.
