performing a first function corresponding to the detected first touch input; detecting a second touch input while the first touch input is maintained; and performing a second function corresponding to the detected second touch input. ### Claim 2 (depends on 1) The method of claim 1, wherein the second function is a function related to the first function. ### Claim 3 (depends on 2) The method of claim 2, wherein the first touch input is a touch event that selects at least one specific object in a home screen or a list screen, and the first function is a function of editing the home screen or the list screen. ### Claim 4 (depends on 3) The method of claim 3, wherein the second touch input is a touch movement event that is generated in the home screen or the list screen, and the second function is a function of moving the home screen or the list screen corresponding to the touch movement event while maintaining a movement of the selected at least one specific object. ### Claim 5 (depends on 4) The method of claim 4, further comprising: when the first touch input is released, changing a location of the at least one selected specific object to a location in which the first touch input is released. ### Claim 6 (depends on 2) The method of claim 2, wherein the first touch input is a touch event that selects at least one specific page in an electronic book content execution screen, and the first function is a function of adding a bookmark to the selected specific page. ### Claim 7 (depends on 6) The method of claim 6, wherein the second touch input is a touch movement event that moves a page of an electronic book content, and the second function is a function of moving the page of the electronic book content corresponding to the touch movement event. ### Claim 8 (depends on 7) The method of claim 7, further comprising: when the page is moved to a previous or a next page and a touch movement event of the first touch input is inputted, moving to a page to which the bookmark is added. ### Claim 9 (depends on 6) The method of claim 6, further comprising: when the first touch input is released, removing the bookmark added to the specific page. ### Claim 10 An apparatus for providing a multi touch interaction in a portable terminal, comprising: a touch panel; and a controller configured to perform a first function corresponding to a first touch input detected on the touch panel and configured to perform a second function corresponding to a second touch input when the second touch input is detected while the first touch input is maintained. ### Claim 11 (depends on 10) The apparatus of claim 10, wherein the second function is a function related to the first function. ### Claim 12 (depends on 11) The apparatus of claim 11, wherein the first touch input is a touch event that selects at least one specific object in a home screen or a list screen, and the first function is a function of editing the home screen or the list screen. ### Claim 13 (depends on 12) The apparatus of claim 12, wherein the second touch input is a touch movement event that is generated in the home screen or the list screen, and the second function is a function of moving the home screen or the list screen corresponding to the touch movement event while maintaining a movement of the selected at least one specific object. ### Claim 14 (depends on 13) The apparatus of claim 13, wherein, when the first touch input is released, the controller changes a location of the selected at least one specific object to a location in which the first touch input is released. ### Claim 15 (depends on 11) The apparatus of claim 11, wherein the first touch input is a touch event that selects a specific page in an electronic book content execution screen, and the first function is a function of adding a bookmark to the selected specific page. ### Claim 16 (depends on 15) The apparatus of claim 15, wherein the second touch input is a touch movement event that moves a page of an electronic book content, and the second function is a function of moving the page of the electronic book content corresponding to the touch movement event. ### Claim 17 (depends on 16) The apparatus of claim 16, wherein, when the page is moved to a previous or a next page and a touch movement event of the first touch input is inputted, the controller outputs to a page to which the bookmark is added. ### Claim 18 (depends on 15) The apparatus of claim 15, wherein, when the first touch input is released, the controller removes the bookmark added to the specific page. ### Claim 19 (depends on 1) A computer-readable storage medium encoded with instructions that, when executed, cause a device to execute the method of claim 1.
