Synopsis

popupMenu [-allowOptionBoxes boolean] [-altModifier boolean] [-button int] [-ctrlModifier boolean] [-deleteAllItems] [-itemArray] [-markingMenu boolean] [-numberOfItems] [-postMenuCommand script] [-postMenuCommandOnce boolean] [-shiftModifier boolean] string

popupMenu is undoable, queryable, and editable.

Popup menus can be added to any kind of control, however, on some widgets, only the standard menu button (3rd mouse button) can be used to trigger popup menus. This is to meet generally accepted UI guidelines that assign the 3rd mouse button and only this one to popup menus, and also to prevent unexpected behavior of controls like text fields, that expect 1st and 2nd button to be reserved for contextual operations like text or item selection...
