**Show Line Numbers**

To show and hide line numbers on the editor, use the ``Show Line Numbers`` and 
``Hide Line Numbers`` items in the ``Edit`` menu.

**Block Commenting**

Use ``Toggle Block Comment`` in the ``Source`` menu to comment out the selected lines of 
code in the current editor.  Selecting the command a second time will return the
lines to their former uncommented state.

For Python files, the type of commenting used with this feature is configured with the
`Editor > Block Comment Style <script:show_preferences_gui#prefname="gui.block-comment-style">`__ 
preference.  Indented block commenting styles tend to work better when editing code around
commented out lines.

**Line Editing**

The ``Line Editing`` sub-menu of the ``Source`` menu provides some commands for quickly
operating on lines of code:

  **New Line Above** creates a new blank line above the current line, auto-indents,
  and places the caret at the start of the new line.
  
  **New Line Below** works the same way but places the new line below the current line.
  
  **Duplicate Lines Above** duplicates the current lines or lines
  above the current selection.  The caret or selection is left unchanged.

  **Duplicate Lines Below** works the same way but the lines are placed below
  the current selection.
  
  **Move Lines Up** moves the current line or lines upward one line.
  
  **Move Lines Down** moves the current line or lines downward one line.
  
  **Delete Lines** deletes all of the current line or lines, even if the selection
  does not span whole lines.
  
  **Swap Lines** swaps the current line, or the line at the start of the selection,
  and the next line.

**Enclose**

The ``Enclose`` sub-menu of the ``Source`` menu provides commands to enclose the current
selection with ``()``, ``[]``, ``{}``, ``''``, ``""``, or ``<>``.  If there is no
selection, the operation is applied to the text between the caret and the end of
the line.

**Changing Case**

The ``Change Case`` sub-menu of the ``Source`` menu provides commands to convert the case
of the current selection to ``UPPER CASE``, ``lower case``, or ``Title Case``. 

``Toggle Symbol Case`` in the same menu converts the current symbol between
``my_symbol_name``, ``mySymbolName``, and ``MySymbolName`` form.  
~~~
~~~if WINGPRO:
To convert all occurrences of a symbol, use the items in the ``Refactor`` menu instead.

**Zooming In and Out**

The editor font size can be increased and decreased temporarily from the ``Zoom``
sub-menu of the ``Edit`` menu.

If the `Editor > Enable Font Size Zooming <script:show_preferences_gui#prefname="edit.enable-font-zoom">`__ 
preference is enabled, zooming the editor can also be accomplished by holding down the 
``Ctrl`` key (or ``Command`` on OS X) while operating the mouse wheel or track pad.

``Reset Zoom`` in the ``Edit > Zoom`` menu returns the font size to the original.

**Brace Matching**

Wing highlights matching braces in green when the cursor is adjacent to a brace.
Mismatched braces are highlighted in red.

You can cause Wing to select the entire contents of the innermost brace pair from the
current cursor position with ``Match Braces`` in the ``Source`` menu.

Parenthesis, square brackets, and curly braces are matched in all files. Angle brackets
(``<`` and ``>``) are matched only in HTML and XML files.

**Zip and Egg Support**

Source files that are stored in ``.zip`` or ``.egg`` files may be loaded into the
editor as read-only files, during stepping in the debugger, for goto-definition, and as
otherwise needed. However Wing is unable to write to a file within a ``.zip`` or ``.egg``
file.

To open a file through the open file dialog, specify the name of the ``.zip`` or ``.egg``
file and add a ``/`` followed by the name of the file to open.
