Defines the indentation of text from the Left and Right edges of the Help window, and also allows you to set a special indent for the first line, which will be relative to the Left indent.
For example, if the left indent is set to "0.5 cm", and the first line to "-0.5 cm", that will have the effect of a hanging indent of 0.5cm, with the first line flush with the edge of the Help window.
The HelpParaRight element corresponds to the "(Indentation) Right" field, on the Paragraph sub-tab, on the Windows Help tab, of the Style object.
