I've used various Linux OSes for quite some time. One feature I very much like in all of them is the ability to copy something (a word, phrase, URL or whatever) to the clipboard just by highlighting it. No need to right-click and copy. Then whatever was copied can be pasted wherever you want just by middle-clicking. No need to right-click and paste. So, copy/pasting in Linux is so much easier and convenient. Is anything like this available on OS X?
