If the touchpad 11 is being touched, the test 73 is followed by a step 74 in which the relevant function currently associated with the touchpad 11 is performed. If the touchpad 11 is not being touched, the test 73 is followed by a test 75 to determine whether the operator control element 10 or 10A has been displaced in direction 51 or 55 by the first distance.
If the operator control element 10 or 10A has been displaced in direction 51 or 55 by the first distance, the test 75 is followed by a test 76 to determine whether the display 4 is being used to present a list. If the display 4 is not being used to present a list, the test 76 is followed by the test 71. If, by contrast, the display 4 is being used to present a list, the upper or lower list entry adjacent to the current list entry is preselected or selected in a step 77. Step 77 is in turn followed by the test 75.
If the operator control element 10 or 10A has not been displaced in direction 51 or 55 by the first distance, the test 75 is followed by a test 78 to determine whether the operator control element 10 or 10A has been displaced in direction 51 or 55 by the second distance. If the operator control element 10 or 10A has been displaced in direction 51 or 55 by the second distance, the test 78 is followed by a test 79 to determine whether the display 4 is being used to present a list. If the display 4 is not being used to present a list, the test 79 is followed by the test 71. If, by contrast, the display 4 is being used to present a list, the list presented by means of the operator control element 4 is scrolled upward or downward in a step 80. Step 80 is followed by the test 78.
If the operator control element 10 or 10A has not been displaced in direction 51 or 55 by the second distance, the test 78 is followed by a test 81 to determine whether the operator control element 10 or 10A has been displaced in direction 61 or 65 by the first distance. If the operator control element 10 or 10A has been displaced in direction 61 or 65 by the first distance, the test 81 is followed by a test 82 to determine whether the display 4 is being used to present a list. If the display 4 is being used to present a list, the left-hand or right-hand list entry adjacent to the current list entry is preselected or selected in a step 83. Step 83 is in turn followed by the test 81. If the display 4 is not being used to present a list, the test 82 is followed by a test 84 to determine whether the display 4 is being used to display a map presentation. If the display 4 is being used to display a map presentation, the test 84 is followed by a step 85, in which a selection window, as denoted by reference symbol 68 by way of example in
If the operator control element 10 or 10A has not been displaced in direction 61 or 65 by the first distance, the test 81 is followed by a test 86 to determine whether the operator control element 10 or 10A has been displaced in direction 61 or 65 by the second distance. If the operator control element 10 or 10A has been displaced in direction 61 or 65 by the second distance, the test 86 is followed by a test 87 to determined whether the display 4 is being used to present a list. If the display 4 is not being used to present a list, the test 87 is followed by the test 71. If, by contrast, the display 4 is being used to present a list, the list presented by means of the operator control element 4 is scrolled to the left or to the right in a step 88. Step 88 is followed by the test 86.
