The connector pop-up menu is presented when the option key is held down while the mouse is clicked on a connector handle. It contains options which apply to the particular connecting line to which the handle belongs.
The Split Connection option achieves the effect of a connecting line which is segmented. This is useful when you don't want a connecting line to go straight from one box to another because it might go through another box in order to get there, or might not look right for some other reason.
When this option is selected, the connecting line is divided into two connectors which meet at the point where the handle was located. The two connecting lines are actually attached to an invisible connecting box, which is created at the point where the handle was. This connecting box can be selected and moved just as other objects can. Once created, you can draw additional connecting lines from the connecting box to other boxes, just as with normal boxes.
Add Arrowhead and Remove Arrowhead are used to add and remove arrowheads on connecting lines. The option applies to the end of the connecting line nearest the handle on which the menu was popped up. Since the program knows which way the connecting lines are going, it automatically draws the arrowhead pointing in the right direction. If you want arrowheads all or most of the time, it is better to choose a default arrowhead option from the Options menu.
Delete Connection removes the connecting line which the menu was popped up from.
