6. The information processing apparatus according to claim 3 , wherein the processor is further configured to execute the computer readable instructions to erase, when the dragging comes to an end, the display of the cursor and returns the information to be displayed on the display section to the first hierarchy information.

7. The information processing apparatus according to claim 3 , wherein the processor is further configured to execute the computer readable instructions to change, when the information to be displayed on the display section is changed from the first hierarchy information to the second hierarchy information and then the dragging is continued until the other end portion of the cursor goes out of the predetermined region and then enters the predetermined region again, the information to be displayed on the display section from the second hierarchy information to third hierarchy information of a third hierarchy which is a higher hierarchy with respect to the second hierarchy.

8. The information processing apparatus according to claim 3 , wherein the region is set to an end portion of the display section.

9. An Information processing method, comprising:

causing, by a processor, when dragging is carried out through an input interface, a cursor interconnecting a start point and an end point of the dragging to be displayed on a display section in response to the dragging and executing, where a direction from one end portion of the cursor which is a start point side of the dragging to an other end portion of the cursor which is an end point side of the dragging is determined as a direction of the cursor, a first process corresponding to the direction of the cursor for information displayed on the display section;
