Ok, I found it. The function is called 'clipboard-kill-ring-save', while it was bound to function: 'kill-ring-save'. But I can't reset C-c. It was bound via cua-mode and the standard approach, using global-set-key doesn't work. How to remap C-c to another function?

A *Help* has opened and tells which function you had chosen from the menu.


In my version of GNU Emacs 24 I see keyboard shot-cuts displayed for (some of) the menu entries.
