To open: Example - Drag 'My Device' over 'My Function' and wait a moment for the Connector Selector window to appear, continue to drag 'My Device' and let go to place it. The two elements that you are connecting are now shown at the top of the window, with a colour selection button and a scrollable list of available connector types (for example, Association, Realization, Assignment, etc.) Pick a colour first by tapping on the colour button, or pick a connector by using your finger to scroll up or down the list and select by tapping on your choice. That's it. The Connector Selector window will close and your connector is shown. Note: If you have enabled 'Copy connectors to other canvas elements automatically' in the App Settings, the connector will appear in whichever views the elements appear.
