View Option Toggle Buttons
The Link Entity Browser is a tool to easily examine the connections between the different parts of a model. One strategy to do that is to start the investigation on one part or a certain group of parts, so each action in the Link Entity Browser starts with a selection of parts. Parts can be considered as links.

Figure 1.
Each button is modal, that is, you click it once to activate it, and click it again to deactivate it. Active buttons remain active until you specifically deactivate them, so you do not need to worry about them "resetting" after you perform an action such as isolate.

| Option | Name | Effect | 
|---|---|---|
|  | Linked connector entity | If this linked connector entity view option button is active
                                    all connectors linked to the 1st link entities will be taken
                                    into account for the action. It does not matter if the 1st link
                                    entity view option button is active or inactive, its connectors
                                    will still be located. This determination has nothing to do with
                                    any display states. This means that in case of the isolation,
                                        only the connectors which are referenced by the selected
                                        links (1st link entity) are isolated.  Figure 3. | 
|  | Realization | When this option is active, all realizations belonging to the
                                    determined linked connector entities will be taken into account
                                    for the action.  Figure 4. | 
Cumulative Effect of Multiple Options
These options work accumulatively, for example, when both the 1st link entity and 2nd link entity buttons are active, then selecting and isolating a component link displays both it and all of the components connected it. If you had realization, 1st link entity, and 2nd link entity active when you isolated the same component link, then the model would display all of the component links connected to the selected one, as well as graphical representation of the realizations of each connector linking those component links together.
