Instance Method


Places the receiver in context-sensitive help mode.


- (void)activateContextHelpMode:(id)sender;



The object that sent the command.


In this mode, the cursor becomes a question mark, and help appears for any user interface item the user clicks.

Most apps don’t use this method. Instead, apps enter context-sensitive mode when the user presses the Help key. Apps exit context-sensitive help mode upon the first event after a help window is displayed.
