Smart Key - C++ Source Code

When the OO-Browser has been loaded and the press is within a C++
buffer:
  ACTION KEY or ASSIST KEY
     Jumps to the definition of the selected C++ construct via
     OO-Browser support.
     (1) on a #include statement, the include file is displayed;
         this looks for include files using the directory lists
         ‘smart-c-cpp-include-path’ and
         ‘smart-c-include-path’;
     (2) within a method definition before the opening brace, its
         declaration is displayed; 
     (3) within a method declaration, its definition is displayed;
     (4) on a class name, the class definition is shown;
     (5) on a member reference (past any :: scoping operator), the
         member definition or a listing of possible definitions or a
         matching declaration (if no definitions exist within the
         Environment) is shown;
     (6) on a global variable or function identifier, its definition is
         shown.

When pressed within a C++ source code file (without the OO-Browser):
  ACTION KEY
     Jumps to the definition of the selected C++ construct:
     (1) on a #include statement, the include file is displayed;
         this looks for include files using the directory lists
         ‘smart-c-cpp-include-path’ and
         ‘smart-c-include-path’;
     (2) on a C++ identifier, the identifier definition is displayed,
         assuming the identifier is found within an "etags" generated
         tags file in the current directory or any of its ancestor
         directories;
     (3) if ‘smart-c-use-lib-man’ is non-nil (see its documentation),
         the C++ identifier is recognized as a library symbol, and a man
         page is found for the identifier, then the man page is
         displayed.
  ASSIST KEY
     Jumps to the next tag matching an identifier at point.
