First and second selection modes

In DynRisk objects are selected in one of two different selection modes: “First selection” and “Second selection”. Objects selected using “First selection” are hilited, while objects selected using “Second selection” are outlined.

Current selection mode is set by choosing “First selection” or “Second selection” from the “Windows” menu or clicking the corresponding buttons in the toolbar. The menu item reflecting the current selection mode is check marked, and the corresponding toolbar button is hilited. You may also alternate between the selection modes by pressing the Tab key.

Having selected a set of objects, you can choose some command acting on these objects. For most commands the selection mode is irrelevant. The action resulting from such commands applies to the objects selected in the current selection mode and does not depend on which selection mode this is. Examples of such commands are “Duplicate”, “Move” and others. Hence, if you e.g., choose “Duplicate” while being in the “Second selection” mode, all outlined objects will be duplicated. Doing the same while in the “First selection” mode duplicates all hilited objects. 

For other commands such as “Connect nodes”, “Distribute”, and “Scatter plot” the selection modes are of specific relevance. If e.g., Node A is selected in first selection mode (i.e., hilited), Node B is selected in second selection mode (i.e., outlined), and the current selection mode is “Second selection”, then the “Connect nodes” command will create an edge from Node A to Node B. If, on the other hand current selection mode is “First selection”, then the same command will create an edge from Node B to Node A.

The “First selection” and “Second selection” buttons are present in all toolbars except the “Help toolbar” and the “No document toolbar”.
