"| This file brings Notepad-like CTRL-ZXCV shortcuts to Vim, while preserving
"| all other Vim shortcuts -- like the CUA-mode does on Emacs:
"|           http://www.emacswiki.org/CuaMode
"|
"| It is based on Bram Molenaar's mswin.vim, g:cua_mode sets the behavior:
"|   0. raw
"|   1. CUA mode     =   (default)  CTRL-ZXCV -- subset of mswin.vim
"|   2. mswin mode   =   CUA mode + CTRL-ASY  -- strict equivalent of mswin.vim
"|   3. Notepad mode = mswin mode + CTRL-QOF  -- superset of mswin.vim
