This extension implements a pane at the top of each IDLE edit window which provides block structure hints. These hints are the lines which contain the block opening keywords, e.g. 'if', for the enclosing block. The number of hint lines is determined by the maxlines variable in the codecontext section of config-extensions.def. Lines which do not open blocks are not shown in the context hints pane. For EditorWindows, <> is bound to CodeContext(self). toggle_code_context_event.

Initially None, it is toggled via <>. self.topvisible is the number of the top text line displayed. self.info is a list of (line number, indent level, line text, block keyword) tuples for the block structure above topvisible. self.info[0] is initialized with a 'dummy' line which starts the toplevel 'block' of the module. self.t1 and self.t2 are two timer events on the editor text widget to monitor for changes to the context text or editor font.
