Locking/Unlocking of the Properties Panel

Some behaviors like e.g. the ForwardValue behavior have a property TargetNode. The appropriate TargetNode can be assigned by pressing the respective icon button, which will open the "Choose Item" dialog as shown in a Behavior example.

There is an alternative - possibly more comfortable - way to configure the TargetNode via drag & drop.

1. Select the object to display the TargetNode to be configured in the properties panel.
2. In the Properties panel: Click the lock button in the top right corner to lock the panel. (As long as this panel is locked, it will display the properties of the object that was selected at the time it was locked.)
3. In the Scene Tree panel: Navigate to the node that you want to configure as TargetNode.
4. Drag this node from the Scene Tree panel and drop it onto the TargetNode property.
5. In the Properties panel: Click the lock button again to unlock the panel.
