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 [OK] 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).
