[TYPO3] how to copy content element?

[Bing Du]

Hi,

I've been using Typo3 for a couple of years.  Now I just realized I don't
know how to copy a content element.  the icons I see for each content
elements are 'Edit','New record after this one','Move record up', 'Move
record down', 'Hide' and 'Delete'.

Thanks in advance.
