outli-mode is a simple minor-mode using outline-minor-mode to support configurable special comment lines as level-aware outline headings. As in org-mode, headings can be collapsed, navigated, moved, etc. outli styles headings for easy level recognition and provides a org-mode-like header navigation and editing capabilities, including "speed keys" which are activated at the start of headings. Customize `outli-heading-config' to set the "stem" and "repeat" character for comment-based headings and to influence how the headings are styled. Customize `outli-speed-commands' to alter or disable speed keys, which work at the beginning of heading lines only.
