Hello. The other day I was fooling around with my computer, specifically changing default screenshot location, but somehow I managed to change the behavior of cmd+shift+4, which originally shows an area selector and pressing space key changes to window-selection mode (the camera). Now, when I press the keys it automatically starts in camera mode and I have to press space to switch to area selector. I don't know how the heck I managed to change this but I want the default behavior back... how can I fix it? I tried with defaults but I can't find an actual setting for that there.
