+!! Using it all
+Some funky tips on how to use your new setup (taken from cscope_maps.vim):
+{code source=text title="Mapping Overview"}
+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
+To do the first type of search, hit 'CTRL-\', 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.
+Using 'CTRL-spacebar' (intepreted as CTRL-@ by vim) then a search type
+makes the vim window split horizontally, with search result displayed in
+the new window.
+Hitting CTRL-space *twice* before the search type does a vertical
+split instead of a horizontal one (vim 6 and up only)
+As you can see above, there's many new ways to now navigate your project. Very cool stuff happens when you move the curson over a function like __verifyPackage__ in wiki/edit.php and then do:
+# vim wiki/edit.php +/verifyPackage (open the file on the first occurrance of verifyPackage)
+# n (to move the cursor to verifyPackage)
+# <CTRL-\>s (this will search the database for all occurances of verifyPackage)
+# :copen (will open a window with a list of all occurrances of verifyPackage)
+# navigate to the occurrance you're interested in and hit <enter>
+# <CTRL-O> (move backward in your jump history - might need to hit this more than once to return to edit/wiki.php)
+# <CTRL-I> (move forward in your jump history)
