+IDLE is the Python IDE built with the tkinter GUI toolkit.
+
+IDLE has the following features:
+-coded in 100% pure Python, using the tkinter GUI toolkit
+-cross-platform: works on Windows, Unix, and OS X
+-multi-window text editor with multiple undo, Python colorizing, smart indent,
+call tips, and many other features
+-Python shell window (a.k.a interactive interpreter)
+-debugger (not complete, but you can set breakpoints, view and step)
+
+Menus:
+
+IDLE has two window types the Shell window and the Editor window. It is
+possible to have multiple editor windows simultaneously. IDLE's
+menus dynamically change based on which window is currently selected. Each menu
+documented below indicates which window type it is associated with. Click on
+the dotted line at the top of a menu to "tear it off": a separate window
+containing the menu is created (for Unix and Windows only).

Basic editing and navigation:
- Backspace deletes char to the left; DEL deletes char to the right.
- Control-backspace deletes word left, Control-DEL deletes word right.
- Arrow keys and Page Up/Down move around.
- Control-left/right Arrow moves by words in a strange but useful way.
- Home/End go to begin/end of line.
- Control-Home/End go to begin/end of file.
- Some useful Emacs bindings are inherited from Tcl/Tk:
- Control-a beginning of line
- Control-e end of line
- Control-k kill line (but doesn't put it in clipboard)
- Control-l center window around the insertion point
- Standard Windows bindings may work on that platform.
- Keybindings are selected in the Settings Dialog, look there.

Automatic indentation:
- After a block-opening statement, the next line is indented by 4 spaces
- (in the Python Shell window by one tab). After certain keywords
- (break, return etc.) the next line is dedented. In leading
- indentation, Backspace deletes up to 4 spaces if they are there. Tab
- inserts spaces (in the Python Shell window one tab), number depends on
- Indent Width. (N.B. Currently tabs are restricted to four spaces due
- to Tcl/Tk issues.)

See also the indent/dedent region commands in the edit menu.
Completions:
- Completions are supplied for functions, classes, and attributes of
- classes, both built-in and user-defined. Completions are also provided
- for filenames.
-
- The AutoCompleteWindow (ACW) will open after a predefined delay
- (default is two seconds) after a '.' or (in a string) an os.sep is
- typed. If after one of those characters (plus zero or more other
- characters) you type a Tab the ACW will open immediately if a possible
- continuation is found.
-
- If there is only one possible completion for the characters entered, a
- Tab will supply that completion without opening the ACW.
-
- 'Show Completions' will force open a completions window. In an empty
- string, this will contain the files in the current directory. On a
- blank line, it will contain the built-in and user-defined functions and
- classes in the current name spaces, plus any modules imported. If some
- characters have been entered, the ACW will attempt to be more specific.
-
- If string of characters is typed, the ACW selection will jump to the
- entry most closely matching those characters. Entering a Tab will cause
- the longest non-ambiguous match to be entered in the Edit window or
- Shell. Two Tabs in a row will supply the current ACW selection, as
- will Return or a double click. Cursor keys, Page Up/Down, mouse
- selection, and the scrollwheel all operate on the ACW.
-
- 'Hidden' attributes can be accessed by typing the beginning of hidden
- name after a '.'. e.g. '_'. This allows access to modules with
- '__all__' set, or to class-private attributes.
-
- Completions and the 'Expand Word' facility can save a lot of typing!
-
- Completions are currently limited to those in the namespaces. Names in
- an Edit window which are not via __main__ or sys.modules will not be
- found. Run the module once with your imports to correct this
- situation. Note that IDLE itself places quite a few modules in
- sys.modules, so much can be found by default, e.g. the re module.
-
- If you don't like the ACW popping up unbidden, simply make the delay
- longer or disable the extension. OTOH, you could make the delay zero.
-
- You could also switch off the CallTips extension. (We will be adding
- a delay to the call tip window.)

+ Alt-/ expand word is also useful to reduce typing.
Command history:
- Alt-p retrieves previous command matching what you have typed.
- Alt-n retrieves next.
- (These are Control-p, Control-n on OS X)
- Return while cursor is on a previous command retrieves that command.
- Expand word is also useful to reduce typing.
+ Alt-p retrieves previous command matching what you have typed. On OS X

Syntax colors:
- The coloring is applied in a background "thread", so you may
- occasionally see uncolorized text. To change the color
- scheme, use the Configure IDLE / Highlighting dialog.

Python default syntax colors:
- Keywords orange
- Builtins royal purple
- Strings green
- Comments red
- Definitions blue

Shell default colors:

Other preferences:
- The font preferences, keybinding, and startup preferences can
- be changed using the Settings dialog.
+ The font preferences, highlighting, keys, and general preferences can
+ be changed via the Configure IDLE menu option. Be sure to note that
+ keys can be user defined, IDLE ships with four built in key sets. In
+ addition a user can create a custom key set in the Configure IDLE
+ dialog under the keys tab.
Command line usage:
- Enter idle -h at the command prompt to get a usage message.
-
-Running without a subprocess:
-
- If IDLE is started with the -n command line switch it will run in a
- single process and will not create the subprocess which runs the RPC
- Python execution server. This can be useful if Python cannot create
- the subprocess or the RPC socket interface on your platform. However,
- in this mode user code is not isolated from IDLE itself. Also, the
- environment is not restarted when Run/Run Module (F5) is selected. If
- your code has been modified, you must reload() the affected modules and
- re-import any specific items (e.g. from foo import baz) if the changes
- are to take effect. For these reasons, it is preferable to run IDLE
- with the default subprocess if at all possible.
+ Enter idle -h at the command prompt to get a usage message.
+
+ idle.py [-c command] [-d] [-e] [-s] [-t title] [arg] ...
+
+ -c command run this command
+ -d enable debugger
+ -e edit mode; arguments are files to be edited
+ -s run $IDLESTARTUP or $PYTHONSTARTUP first
+ -t title set title of shell window
+
+ If there are arguments:
+ 1. If -e is used, arguments are files opened for editing and sys.argv
+ reflects the arguments passed to IDLE itself.
+ 2. Otherwise, if -c is used, all arguments are placed in
+ sys.argv[1:...], with sys.argv[0] set to -c.
+ 3. Otherwise, if neither -e nor -c is used, the first argument is a
+ script which is executed with the remaining arguments in
+ sys.argv[1:...] and sys.argv[0] set to the script name. If the
+ script name is -, no script is executed but an interactive Python
+ session is started; the arguments are still available in sys.argv.
+
