Navigation |

Navigation is controlled by tabs displayed at the top of each page. Tabs can be active, inactive or invisible.
An inactive tab indicated that the function is installed but is not available to the current user, usually because this user does not have the appropriate permissions.
To navigate the user interface, a tab must be selected, followed by a sub-tab. Most sub-tabs give access to a menu of functions. When 'frames' are active, the bottom part of the screen usually include a left frame where this menu is always available and a right frame when the functions are displayed.
With 'frames' off, the left frame is not available and is replaced by bread crumbs on the main function page.
