;; * Keybindings:
;;
;; All keybindings use the "C-c s" prefix, but are usable only while
;; editing a source file, or in the cscope results buffer:
;;
;; C-c s s Find symbol.
;; C-c s d Find global definition.
;; C-c s g Find global definition (alternate binding).
;; C-c s G Find global definition without prompting.
;; C-c s c Find functions calling a function.
;; C-c s C Find called functions (list functions called
;; from a function).
;; C-c s t Find text string.
;; C-c s e Find egrep pattern.
;; C-c s f Find a file.
;; C-c s i Find files #including a file.
;;
;; These pertain to navigation through the search results:
;;
;; C-c s b Display *cscope* buffer.
;; C-c s B Auto display *cscope* buffer toggle.
;; C-c s n Next symbol.
;; C-c s N Next file.
;; C-c s p Previous symbol.
;; C-c s P Previous file.
;; C-c s u Pop mark.
;;
;; These pertain to setting and unsetting the variable,
;; `cscope-initial-directory‘, (location searched for the cscope database
;; directory):
;;
;; C-c s a Set initial directory.
;; C-c s A Unset initial directory.
;;
;; These pertain to cscope database maintenance:
;;
;; C-c s L Create list of files to index.
;; C-c s I Create list and index.
;; C-c s E Edit list of files to index.
;; C-c s W Locate this buffer‘s cscope directory
;; ("W" --> "where").
;; C-c s S Locate this buffer‘s cscope directory.
;; (alternate binding: "S" --> "show").
;; C-c s T Locate this buffer‘s cscope directory.
;; (alternate binding: "T" --> "tell").
;; C-c s D Dired this buffer‘s directory.
