;;; Commentary:
;; indentation bits extracted from original Dave Love's python.el
;; found in GNU/Emacs.
-;; While it probably has less features than Dave Love's python.el and
-;; PSF's python-mode.el it provides the main stuff you'll need while
-;; keeping it simple :)
-
;; Implements Syntax highlighting, Indentation, Movement, Shell
;; interaction, Shell completion, Shell virtualenv support, Pdb
;; tracking, Symbol completion, Skeletons, FFAP, Code Check, Eldoc,
;; Movement: `beginning-of-defun' and `end-of-defun' functions are
;; properly implemented. There are also specialized
-;; `forward-sentence' and `backward-sentence' replacements
-;; (`python-nav-forward-sentence', `python-nav-backward-sentence'
-;; respectively). Extra functions `python-nav-sentence-start' and
-;; `python-nav-sentence-end' are included to move to the beginning and
-;; to the end of a setence while taking care of multiline definitions.
-;; `python-nav-jump-to-defun' is provided and allows jumping to a
-;; function or class definition quickly in the current buffer.
+;; `forward-sentence' and `backward-sentence' replacements called
+;; `python-nav-forward-block', `python-nav-backward-block'
+;; respectively which navigate between beginning of blocks of code.
+;; Extra functions `python-nav-forward-statement',
+;; `python-nav-backward-statement',
+;; `python-nav-beginning-of-statement', `python-nav-end-of-statement',
+;; `python-nav-beginning-of-block' and `python-nav-end-of-block' are
+;; included but no bound to any key. At last but not least the
+;; specialized `python-nav-forward-sexp' allows easy
+;; navigation between code blocks.
;; Shell interaction: is provided and allows you to execute easily any
;; block of code of your current buffer in an inferior Python process.
