The PJC for the pushbutton adds a focusborder to the button and causes the shortcut key, if not included in the label, to be attached to the label and the tooltip.
Furthermore, it is possible to define jumps (Gotobean) for the button, to switch to other items or modules of the Forms application.
A further extension is the rounded representation of the leftmost and rightmost button in a group of buttons, as can be seen on the picture below.
