How do I take a screenshot without the shadow behind it?
I know this is an old question - but I can never find this information when searching for it (just the information in the accepted answer to turn it off globally), and end up just trying random keys each time.
If you hold option while clicking (after doing the Shift ⇧ + Command ⌘ + 4, Space dance), the saved screenshot will not have the drop shadow.
I'm unsure if this only applies to Mountain Lion and later.
