 **Debugging** in Spyder is supported through integration with the enhanced ``ipdb`` debugger in the :doc:`ipythonconsole`.
 This allows breakpoints and the execution flow to be viewed and controlled right from the Spyder GUI, as well as with all the familiar IPython console commands.

 Spyder's debugger offers syntax highlighting, code completion and command history, which work exactly like they do in the normal interactive interpreter.
 
 Use the up and down arrows to recall previous commands, and press :kbd:`Tab` to trigger autocomplete suggestions.

 Furthermore, IPython's `magic functions`_ are available in debugging mode.
 You can, for example, run ``%ls`` to list the contents of your current working directory or ``%timeit`` to check how fast a given snippet of code is.

 You can avoid stepping through other Python packages while debugging by enabling the new :guilabel:`Ignore Python libraries while debugging` option in Spyder's preferences, under :menuselection:`IPython Console --> Debugger --> Debug`.
 This will skip all the built-in and third-party Python modules you have installed.

 If your code has variables with the same names as Pdb commands (e.g. ``b`` or ``step``), you can still refer to them as normal while debugging.
 To call the respective Pdb command, just add an exclamation point before it (e.g. ``!b`` or ``!step``).

 You can have Spyder automatically execute a custom snippet of code every time the debugger stops.
 For example, you can use this to set specific variables, or import commonly-used modules so they are always available while debugging.
 To set this up, go to :menuselection:`Preferences --> IPython Console --> Debugger --> Run code while debugging`, and enter the code that you want to be executed with each step.
