Using the X window system, highlighting text puts it in the PRIMARY
selection. On windows, highlighting text does nothing.

Using the X window system, highlighting text then pressing CTRL-C puts
the content into the CLIPBOARD selection. On windows, though, that
action puts the text into the PRIMARY selection.

vim, just like emacs, is an old software using old paradigms. They use
their own buffers to copy and paste content, unrelated to the X window
system. They can be made to store the text to an external buffer though.

xterm doesn't have CTRL-C because that shortcut can potentially be used
by the terminal itself. (i.e. will kill the running process.)
