The messages M1 and M3 corresponding to the search word among the messages of the list disappearing from the main display 400 are sorted and sequentially displayed on the second sub display 600 as compared with the search word ].

More specifically, as the list is scrolled, the message M1 is compared with the search term at the moment when one message (e.g., M1) disappears from the main display 400. [ If the message M1 corresponds to the search word, the message disappears from the main display 400 and is displayed on the second sub display 600. If the message M1 does not correspond to the search word, the message M1 disappears from the main display 400. [

When the message M1 is disappeared, the message M2 of the next order is displayed at the moment when the next message (for example, M2) disappears from the main display 400 as the list is scrolled, . The procedure below is the same as described above.

Accordingly, if the speed of the touch dragging is fast, the list is quickly scrolled so that scrolled messages in the list are quickly sorted. If the speed of the touch dragging is slow, the list is scrolled slowly, .

When the message corresponds to the search word and is sorted into the second sub display 600, a visual effect for informing the message sorting is displayed on the main display 400, the first sub display 500, and the second sub display 600 It may occur in at least one display, or an effect sound or vibration may be generated. At least one of the visual effect, sound effect, and vibration may be generated each time a message is sorted.

Then, one message among the messages displayed on the second sub-display 600 is selected by touching.

Then, as shown in (13-5) of FIG. 13, the content of the selected message is displayed on the main display 400.

In the above description, when the main display 400 is performing the touch dragging, only a number of messages proportional to the touch dragging are sequentially compared with the search word while being deleted from the main display 400. [ However, the present embodiment is not limited to this, and when the main display 400 performs the touch dragging, all the messages in the list may be sequentially compared with the search word and disappear from the main display 400 and may be sorted.
