Thank you for the response, but this does not answer my question. There appears to be two groups of styles - list styles created under the dropdown from the outline numbering button, and styles created from the "New Style" button in the styles pane. They do not seem to link, and styles created from the outline numbering button do not appear in the styles pane.
Also styles using a custom outline numbering scheme do not respond to using TAB to change the outline level.
I cannot find any guidance for Mac how to do the linking available in the Windows version
Windows has the option in customising outline style to line a level in the numbering scheme to a style from the style panel - e.g. link level 1 to the Heading 1 style. The Mac version of rod does not set to have this??
