5 Mouse button switching modesYou can use a three button mouse to switch between systems. However, whenused in this way, the action of the middle mouse button or scroll wheel clickis ‘trapped’ by the Adder unit and is not passed to the system. This makes itunavailable for use in controlling applications on the selected system. The scrollwheel scrolling action is unaffected and passed on normally to the systems, onlythe scroll wheel click is used by the Adder unit.• To use the mouse buttons to change systems, use options U1 (default) orU4.• To use the scroll wheel click/third mouse button with the systems, useoptions U3 or U5.• To report only a simple 2-button mouse to the systems, use option U2.To change the mouse button switching modes1 Enter configuration mode: Press and hold the SELECT button until the SYSTEMreadout shows c.2 Press followed by a number to select the required mouse button setting,as follows:System channels are switchable using a 3-button mouse orIntelliMouse (default).
