      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 "

     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
     82     " files that contain 'time.h' as part of their name).
     83 
     84 
     85     " To do the first type of search, hit 'CTRL-\', followed by one of the
     86     " cscope search types above (s,g,c,t,e,f,i,d).  The result of your cscope
     87     " search will be displayed in the current window.  You can use CTRL-T to
     88     " go back to where you were before the search.
