Left+Dragging the endpoint of a turnout (or other sectional track) causes a straight length of flex-track to be created from the selected endpoint to the cursor.
Left+Dragging the endpoint of a Table Edge (Section 2.3) allows the endpoint to be moved to a new position. If the endpoint is moved close to another Table Edge then the endpoint will be moved to it.
The length of a curved track can be changed to form an almost complete circle by selecting one endpoint of the curved track then dragging the cursor to the other endpoint. Going past the other endpoint creates a very small curve. Curves greater than 360° cannot be created.
