with \1, \2, etc.
\%( \) - Non capturing group

##Surround plugin

ys<motion or text><char to wrap> - Surrounds the text in the motion
(Example: w for to the next word or $ to the end of the line) with
the character, HTML tag, etc.
cs<old char><new char> - Changes the surrounding character
cst<html tag> - Changes an html tag from the current to a new one
ctrl-s - Adds a surrounding in insert mode

:Gw - Saves and git adds
:Gco or :Gcommit - Commits
