The MouseButton2Down event fires when the user presses their left Mouse button down on the GUI object.

This event is similar to GuiButton/MouseButton1Down, which behaves identically except that it is connected to the user’s left mouse button.

If you are looking for an event requiring the user to press and release their right mouse on a GUI in order for the event to fire, consider using GuiButton/MouseButton2Click.

Note that this event will only fire for GUI buttons, including TextButton|TextButtons and ImageButton|ImageButton. It will not fire for other GuiObject|GuiObjects.

Handling Left Mouse Button Up/Down on a GUI Button

The code sample below demonstrates how to use the GuiButton/MouseButton2Up and GuiButton/MouseButton2Down events to handle user input when the right mouse button is pressed down and released up on a GuiButton.

For the example to work expected, the LocalScript containing the code should be a child of the GUI button.
