Copy

The User Interface > Preview/Edit Window > Text/Edit Tab > Editor Toolbar... > Copy

Copies the selected data to the Clipboard.  See the above warning, but then again, sometimes this is just what you want to do.  For example, you might have a Clip containing several sentences, but you only want one.  Highlight the one you want, hit the Copy button, and you will get a brand new Clip containing just the data that you need.
