Smart Key - Objective-C Source Code

When the OO-Browser has been loaded and the press is within a
Objective-C buffer:
  ACTION KEY or ASSIST KEY
     Jumps to the definition of the selected Objective-C construct via
     OO-Browser support.
     (1) on a #import or #include statement, the include file is
         displayed; this looks for include files using the directory
         lists ‘objc-cpp-include-path’ and
         ‘objc-include-path’;
     (2) within a method declaration, its definition is displayed;
     (3) on a class name, the class definition is shown;
     (4) on a member reference (past any :: scoping operator), the
         member definition or a listing of possible definitions is
         shown;
     (5) on a global variable or function identifier, its definition
         is shown.

When pressed within an Objective-C source code file (without the
OO-Browser):
  ACTION KEY
     Jumps to the definition of the selected Objective-C construct:
     (1) on a #import or #include statement, the include file is
         displayed; this looks for include files using the directory
         lists ‘objc-cpp-include-path’ and
         ‘objc-include-path’;
     (2) on an Objective-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 Objective-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.
