Click with middle button

[humitos]

When you click on a link with the middle button the new page is loaded in the same tab instead opening a new one.

The default behaviour of Epiphany is "open the link in a new tab"

Use the middle button is outside of the scope of the Sugar design guidelines (in the same category as double clicks).

Yes, as Walter said, Sugar design is not intended to be used with a three buttons mouse, not even a mouse, only trackpad with two buttons.

From  http://wiki.sugarlabs.org/go/Human_Interface_Guidelines/The_Sugar_Interface/Input_Systems#Trackpad

the laptops have two buttons positioned beneath the trackpad for input. The left button is the primary button with which elements of the interface are selected, pressed, or activated. The right button has secondary functionality. Typically, the right mouse button invokes contextual menus, the content of which pertains directly to the interface element the mouse is positioned over.

As we move towards touch support, et al., to add dependencies on more mouse buttons seems like a step in exactly the wrong direction.
