+ " The following maps all invoke one of the following cscope search types:
+ "
+ " 's' symbol: find all references to the token under cursor
+ " 'g' global: find global definition(s) of the token under cursor
+ " 'c' calls: find all calls to the function name under cursor
+ " 't' text: find all instances of the text under cursor
+ " 'e' egrep: egrep search for the word under cursor
+ " 'f' file: open the filename under cursor
+ " 'i' includes: find files that include the filename under cursor
+ " 'd' called: find functions that function under cursor calls
+ "
+ " All of the maps involving the <cfile> macro use '^<cfile>$': this is so
+ " that searches over '#include <time.h>" return only references to
+ " 'time.h', and not 'sys/time.h', etc. (by default cscope will return all
+ " files that contain 'time.h' as part of their name).
+
+ " To do the first type of search, hit the leader key, followed by one of
+ " the cscope search types above (s,g,c,t,e,f,i,d). The result of your
+ " cscope search will be displayed in the current window. You can use
+ " CTRL-T to go back to where you were before the search.
