Click on a group you wish to administrate: the list of available rights appears in the bottom window and those are classified by categories (global, display, etc.)
To change rights, you just have to choose the category, and then select the right you wish to modify. Afterwards, click on the “Value” column. A scrolling menu appears: this menu offers the possibility to assign the right to the desired category.
There are three statuses for each right:
Yes: grants possibility to assign the right
No: grants possibility to retain the right
Undefined: grants possibility not to define the right (used for power groups)
