That would be good but then I should use two different key bindings for
pasting, which is a bit annoying.
I also found this variable (by the way, how to you write with that nice
style?
This "cut here" is a bit too much...
--8<---------------cut here---------------start------------->8---
x-select-enable-clipboard is a variable defined in `C source code'.
It is void as a variable.

Documentation:
Non-nil means cutting and pasting uses the clipboard.
This is in addition to, but in preference to, the primary selection.
--8<---------------cut here---------------end--------------->8---

Would not be possible to avoid overwriting the clipboard entry with the
last entry killed?

Or is there a way to understand from emacs if something is copied on the
on the operating system clipboard?
