contextmenu

The contextmenu event is fired when the right button of the mouse is clicked (before the context menu is displayed), or when the context menu key is pressed (in which case the context menu is displayed at the bottom left of the focused element, unless the element is a tree, in which case the context menu is displayed at the bottom left of the current row).

Default Action

In Gecko this event is handled by a XUL ancestor element, even for HTML5 context menus, which are actually handled by the browser element's context menu. If a XUL ancestor element has a context or contextmenu attribute referencing a popup, then display it (subject to the popupshowing event).

button Read only	unsigned short	The button number that was pressed when the mouse event was fired: Left button=0, middle button=1 (if present), right button=2. For mice configured for left handed use in which the button actions are reversed the values are instead read from right to left.
