3.4 Getting Help
================

DDD has an extensive on-line help system.  Here's how to get help while
working with DDD.

   * You can get a short help text on most DDD buttons by simply moving
     the mouse pointer on it and leave it there.  After a second, a
     small window (called "button tip"; also known as "tool tip" or
     "balloon help") pops up, giving a hint on the button's meaning.
     The button tip disappears as soon as you move the mouse pointer to
     another item.

   * The "status line" also displays information about the currently
     selected item.  By clicking on the status line, you can redisplay
     the most recent messages.

   * You can get detailed help on any visible DDD item.  Just point on
     the item you want help and press the `F1' key.  This pops up a
     detailed help text.

   * The DDD dialogs all contain `Help' buttons that give detailed
     information about the dialog.

   * You can get help on debugger commands by entering `help' at the
     debugger prompt.  Note: Entering Commands, for details on
     entering commands.

   * If you are totally stuck, try `Help => What Now?' (the `What Now?'
     item in the `Help' menu) or press <Ctrl+F1>.  Depending on the
     current state, DDD will give you some hints on what you can do
     next.

   * Of course, you can always refer to the _on-line documentation_:

        - `Help => DDD Reference' gives you access to the DDD manual,
          the ultimate DDD reference.

        - `Help => Debugger Reference' shows you the on-line
          documentation of the inferior debugger.

        - `Help => DDD WWW Page' gives you access to the latest and
          greatest information on DDD.  

   * Finally, the DDD "Tip Of The Day" gives you important hints with
     each new DDD invocation.  

   All these functions can be customized in various ways (Note:
Customizing Help).

   If, after all, you made a mistake, don't worry: almost every DDD
command can be undone.  Note: Undo and Redo, for details.
