Let's be careful with our definitions here
- An Emacs copy is the command
kill-ring-save(usually bound to M-w).
- A system copy is what you typically get from pressing C-c (or choosing "Edit->Copy" in a application window).
- An X copy is "physically" highlighting text with the mouse cursor.
- An Emacs paste is the command
yank(usually bound to C-y).
- A system paste is what you typically get from pressing C-v (or choosing "Edit-Paste" in an application window).
- An X paste is pressing the "center mouse button" (simulated by pressing the left and right mouse buttons together).
I wonder what "system copy" and "system paste" are? Are they by OS (here Linux)?
So are they different from X copy and X paste?
