Taking screen shots on osx lion
So I have a bit of a n00b question and I did try to google with no helpful answers.
I am trying to take screen shots and when I go into menues I cant work out how to take them... I do try press the shortcuts on the keyboard (for example command Z) as it says taking a screen shot of the whole screen is on the app "grab" in utilities and when I do manage to get the little pointer and select the place to take a picture I have no idea where its saving to.. it just snaps and I have no idea where its gone?
TIA
