A method for controlling a cursor on a portable device, the method comprising: detecting a first pressure touch on an input region of an application screen displayed on a touchscreen of the portable device, wherein the application screen includes an input region including a soft key and a display region displaying the cursor and a sentence including text, wherein the text includes words, the words being separated by spaces and each of the words comprising at least one letter; displaying a pressure touch region corresponding to the detected first pressure touch; detecting another pressure touch on the pressure touch region while the first pressure touch is maintained; after the another pressure touch is detected, detecting a continuous movement of the first pressure touch while the another pressure touch is maintained; moving a position of the cursor from a first position between a plurality of letters of a first word in a first line to a second position between a plurality of letters of a second word in a previous line of the first line or from the first position to a third position between a plurality of letters of a third word in a next line of the first line, based on a direction of the continuous movement of the first pressure touch while the another pressure touch is maintained; and highlighting a plurality of letters which are between the first position and the moved position of the cursor; detecting a release of the another pressure touch and displaying at least one function icon (192a, 192b, 192c, 192d, 192e) for editing the highlighted plurality of letters at a side of the first pressure touch corresponding to the release of the another pressure touch, wherein the at least one function icon includes at least one of a select all icon, a cut icon, a copy icon, a paste icon, and a delete icon; selecting one of the displayed at least one function icon (192a, 192b, 192c, 192d, 192e) by the continuous movement of the first pressure touch; and editing the highlighted plurality of letters corresponding to the selected function icon. detecting a first pressure touch on an input region of an application screen displayed on a touchscreen of the portable device, wherein the application screen includes an input region including a soft key and a display region displaying the cursor and a sentence including text, wherein the text includes words, the words being separated by spaces and each of the words comprising at least one letter; displaying a pressure touch region corresponding to the detected first pressure touch; detecting another pressure touch on the pressure touch region while the first pressure touch is maintained; after the another pressure touch is detected, detecting a continuous movement of the first pressure touch while the another pressure touch is maintained; moving a position of the cursor from a first position between a plurality of letters of a first word in a first line to a second position between a plurality of letters of a second word in a previous line of the first line or from the first position to a third position between a plurality of letters of a third word in a next line of the first line, based on a direction of the continuous movement of the first pressure touch while the another pressure touch is maintained; and highlighting a plurality of letters which are between the first position and the moved position of the cursor; detecting a release of the another pressure touch and displaying at least one function icon (192a, 192b, 192c, 192d, 192e) for editing the highlighted plurality of letters at a side of the first pressure touch corresponding to the release of the another pressure touch, wherein the at least one function icon includes at least one of a select all icon, a cut icon, a copy icon, a paste icon, and a delete icon; selecting one of the displayed at least one function icon (192a, 192b, 192c, 192d, 192e) by the continuous movement of the first pressure touch; and editing the highlighted plurality of letters corresponding to the selected function icon.
