The copy-paste tag is used for the clipboard actions Copying and Pasting.
This should be merged with the existing clipboard tag, and synonymised so that future users can find the right tag.
I'm not sure "clipboard" should be the primary term. People think of "clipboard" as a system utility that can be used within or across applications. A big portion of the copy and copy-paste questions relate to things like propagating cell contents in a spreadsheet. Copy-paste is more generic than clipboard.
