Good way to handle multiple clipboard in emacs

Question

I am using the Mac OS command line version Emacs 24.3. And the copy and post in Emacs could be a little messy as the C-k, C-d and other command could replace the content in the clipboard as we use C-y.

I am wondering whether there is a multiple clipboard system like yn and pn in Vim.

Thanks.

Answer 1

Yes, there is a such system called "Registers": http://www.gnu.org/software/emacs/manual/html_node/emacs/Registers.html

Answer 2

There is also a secondary selection. See the Emacs manual, node Secondary Selection. See also Secondary Selection and library second-sel.el, which facilitates using the secondary selection.
