Currently, hitting <control> or <command> + K in the Visual Editor opens a link dialog. This is sub-optimal, as <control>-k is (and has been, for about 30 years) the "kill" command in emacs-like editors. (<ctrl>-k adds to the kill ring, <ctrl>-y pastes the kill ring into the contents).
I suggest that the Visual Editor should support these basic commands by default, without modification via preferences (e.g., "use emacs keybindings"). Activation of the link editor should probably be moved to a more intuitive accelerator anyways ("k" does not suggest "link" to me).
For implementation, the "kill ring" functionality operates thus: <ctrl>-k deletes the current line of text, including the EOL character. This text is copied into the "kill ring" buffer. Additional <ctrl>-k expressions ''add'' to the kill ring; ''any'' other activity (including cursor movement) "closes" the kill ring. At that point, <ctrl>-y will insert the entire contents of the kill ring into the text at the point of the cursor.
