1. An actuating device for actuating gear ratio-changing gear shift units of a manual transmission, comprising:
a plurality of deflectable transmission elements assigned to a respective gear shift unit for changing a gear ratio, the plurality of deflectable transmission elements including a first transmission element, a second transmission element, a third transmission element, and a fourth transmission; and
a movable actuating element having a plurality of gear shift elements assigned thereto, the gear shift elements movable together with the actuating element and which, dependent on a selected selecting position of the actuating element that is variable by a selecting movement of the actuating element, are coupled with coupling means of the transmission elements via a gear shift coupling for deflecting the transmission elements by means of a shifting movement of the actuating element;
wherein the shifting movement is independent of the selecting movement;
wherein the selecting position is changeable in selecting steps that are delimited by a selecting step length;
wherein the plurality of gear shift elements include a first gear shift element, a second gear shift element, a third gear shift element, and fourth gear shift element, the first and second gear shift elements being arranged in a first gear shift group, and the third and fourth gear shift elements being arranged in a second gear shift group;
wherein the first gear shift group engages only the first and third transmission elements, and the second gear shift group engages only the second and fourth transmission elements;
wherein the first and third gear shift elements each have a first interconnected gear shift length which effects the shifting coupling with one of the transmission elements in the corresponding gear shift group and which is greater than the selecting step length; and
wherein the second and fourth gear shift elements each have a second interconnected gear shift length which is different from the first interconnected gear shift length.
