A new role can be added to an object via  Add Role   and for the current folder also via  File    Share    Add Role   . This brings up a form in which you have to specify the name of the role and then either select an already existing role or one more of the eight so-called action classes. Action classes are "Get", "Get extended", "Change", "Change extended", "Share", and "Share extended". In other words: a new role is derived from predefined access rights templates.

After you have specified the name of the role and made a selection from the access rights templates, you may either click the "OK" button which creates the role as an exact copy from the selected template(s), or select "Edit Role" to make modifications to the access rights specifications given by the template(s).
