By automatically registering a related key word when a received message is displayed, past e-mail messages related to the received message can be selected by single-clicking. When a portable telephone receives an e-mail message, the received message is displayed on a display portion. A registering means automatically registers in a storage portion a key word from the received message displayed on the display portion. When a user searches for past sent messages and received messages related to the received message displayed on the display portion, the searching means automatically searches for the key word registered in the storage portion. Hence, desired messages can be searched for and retrieved from past e-mail messages simply by single clicking a software button displayed on a screen. The retrieved messages are displayed on the display portion by a retrieved message display controlling means. The display can be switched between the received message and the retrieved messages simply by single-clicking a software button. |
