A portable electronic device, comprising:

• a touchscreen display including a display area, and
• at least one processor configured to:
• display, on the touchscreen display, a second execution screen of a second application, wherein the second execution screen substantially occupies an entirety of the display area,
• display, on the touchscreen display, a first execution screen of a first application in place of the second execution screen, wherein the first execution screen includes a plurality of objects, and wherein the first execution screen substantially occupies the entirety of the display area,
• identify, on the touchscreen display, a first touch input with respect to a first object among the plurality of objects while the first execution screen substantially occupies the entirety of the display area,
• in response to the first touch input, display, on the touchscreen display, an image corresponding to the first object at a position on the first execution screen corresponding to a position of the first touch input while the first touch input is maintained on the touchscreen display,
• while the first touch input is maintained on the touchscreen display, identify a second touch input received on the first execution screen,
• in response to the second touch input, display the second execution screen on the touchscreen display, wherein, while the second execution screen substantially occupies the entirety of the display area, the image is displayed at a position on the second execution screen corresponding to the position of the first touch input while the first touch input is maintained on the touchscreen display, and
• when the first touch input is released while the image is displayed on the second execution screen, display a second object corresponding to the first object on the second execution screen.

A portable electronic device, comprising:

• a touchscreen display including a display area, and
• at least one processor configured to:
• display, on the touchscreen display, a first execution screen of a first application and a third execution screen of a third application side by side, wherein the first execution screen includes a plurality of objects, and wherein the first execution screen and the third execution screen substantially occupy an entirety of the display area,
• identify, on the touchscreen display, a first touch input with respect to a first object among the plurality of objects while the first execution screen and the third execution screen substantially occupy the entirety of the display area,
• in response to the first touch input, display, on the touchscreen display, an image corresponding to the first object on the first execution screen, wherein the image is displayed at a position on the first execution screen corresponding to a position of the first touch input while the first touch input is maintained on the touchscreen display,
• while the first touch input is maintained on the touchscreen display, identify a second touch input on the touchscreen display,
• in response to the second touch input, display, on the touchscreen display, a second execution screen of a second application, wherein the image is displayed at a position on the second execution screen corresponding to the position of the first touch input, and wherein the second execution screen substantially occupies the entirety of the display area, and
• when the first touch input is released while the second execution screen substantially occupies the entirety of the display area, input a second object corresponding to the first object to the second execution screen.
