   2 " CSCOPE settings for vim
   3 """"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
   4 "
   5 " This file contains some boilerplate settings for vim's cscope interface,
   6 " plus some keyboard mappings that I've found useful.
   7 "
   8 " USAGE:
   9 " -- vim 6:     Stick this file in your ~/.vim/plugin directory (or in a
  10 "               'plugin' directory in some other directory that is in your
  11 "               'runtimepath'.
  12 "
  13 " -- vim 5:     Stick this file somewhere and 'source cscope.vim' it from
  14 "               your ~/.vimrc file (or cut and paste it into your .vimrc).
  15 "
  16 " NOTE:
  17 " These key maps use multiple keystrokes (2 or 3 keys).  If you find that vim
  18 " keeps timing you out before you can complete them, try changing your timeout
  19 " settings, as explained below.
  20 "
  21 " Happy cscoping,

  54     " The following maps all invoke one of the following cscope search types:
  55     "
  56     "   's'   symbol: find all references to the token under cursor
  57     "   'g'   global: find global definition(s) of the token under cursor
  58     "   'c'   calls:  find all calls to the function name under cursor
  59     "   't'   text:   find all instances of the text under cursor
  60     "   'e'   egrep:  egrep search for the word under cursor
  61     "   'f'   file:   open the filename under cursor
  62     "   'i'   includes: find files that include the filename under cursor
  63     "   'd'   called: find functions that function under cursor calls
  64     "
  65     " Below are three sets of the maps: one set that just jumps to your
  66     " search result, one that splits the existing vim window horizontally and
  67     " diplays your search result in the new window, and one that does the same
  68     " thing, but does a vertical split instead (vim 6 only).
  69     "
  70     " I've used CTRL-\ and CTRL-@ as the starting keys for these maps, as it's
  71     " unlikely that you need their default mappings (CTRL-\'s default use is
  72     " as part of CTRL-\ CTRL-N typemap, which basically just does the same
  73     " thing as hitting 'escape': CTRL-@ doesn't seem to have any default use).
  74     " If you don't like using 'CTRL-@' or CTRL-\, , you can change some or all
  75     " of these maps to use other keys.  One likely candidate is 'CTRL-_'
  76     " (which also maps to CTRL-/, which is easier to type).  By default it is
  77     " used to switch between Hebrew and English keyboard mode.
  78     "
  79     " All of the maps involving the <cfile> macro use '^<cfile>$': this is so
  80     " that searches over '#include <time.h>" return only references to
  81     " 'time.h', and not 'sys/time.h', etc. (by default cscope will return all
