Module surround 

surround-mode – vim-surround semantics as a native minor mode.

Three grammar operators: surround-delete (ds{char}), surround-change (cs{char1}{char2}), surround-add (yss{char} / S{char} in visual). All three are registered in the shared CommandRegistry at boot.

register_surround_modes
