I tried `M-x apropos RET current-line' and didn't find anything that
does the job.

Yes.  Of course setting the mark and moving point changes the point,
which you may not want, and involves a 3-key sequence: C-a C-@ C-e.
So you might want to define a keyboard macro, e.g.

(global-set-key "\C-cl" "\C-a\C-@\C-e\M-w")

or bind a key to a new command:

(defun copy-current-line-as-kill ()
   "Save the current line as if killed, but don't kill it.
See `copy-region-as-kill'."
   (interactive)
   (kill-ring-save (point-at-bol) (point-at-eol)))

(global-set-key "\C-cl" 'copy-current-line-as-kill)

You can give a prefix arg to other-window (which is what `C-x o' is
bound to), e.g. `C-u 3 C-x o' or `M-3 C-x o'.
