I understand the concept of a buffer. It is the text that's saved from a file that we edit inside of Vim.

When I use the yy command, where exactly does Vim save this information to?

In any other editor, using the copy command would save it to the clipboard, so does Vim have some kind of clipboard and would that clipboard also be called a buffer of sorts ?

    Read :h registers and :h clipboard.

  • confusingly, long ago, registers were also referred to as "buffers," sometimes "buffer registers" docs.freebsd.org/44doc/usd/12.vi/paper-6.html#section33

    In a different program, though, so no confusion possible unless you confuse the two programs.

By default Vim saves the result into the " register and in the 0.

You can see the content of the " register using the command:

:reg "

Note: The 0 register is only used for the yank operation (i.e. not for the change or delete operation) this allow you to yank a text, delete the text you want to be replaced and past the yanked register using the "0p register.

If you want to have the yanked content into the system clipboard you have to make sure it goes into the * register.

You can do that by either:

  • Specifying the * register when you yank "*yy
  • Set the clipboard option to unnamed (:set clipboard=unnamed)

With the later:

  • Every yank, delete operation using the default register will set the clipboard (*) register
  • Every past operation using the default register will use the clipboard (*) register

    @Rich, I have added some remark about the 0 register. Let me know if you had other idea in mind. Oct 17, 2022 at 16:41
