Some of portable telephones have various additional functions such as an incoming-call sound changing function of changing an incoming-call sound to a desired melody and an address directory function, as well as a communication function. In such a portable telephone, these additional functions are arranged in hierarchically structured menu screens, e.g. as disclosed in US-A-5,797,098, and the menu screens are displayed on a display to allow a user to view them and to select a desired additional function on a menu screen with given operation keys, and thereby the additional function is executed. However, in such a portable telephone, the hierarchically structured menu screens have to be switched to select a desired additional function, in order to execute the desired additional function, which cause a problem in that the operations are complicated because the operation keys have to be operated many times. In addition, some of such portable telephones have execution keys dedicated to additional functions which are supposed to be often used, for example, an incoming-call sound silencing function, and executes the additional functions in response to pushing of the execution keys. However, it is not sure that all users often use the additional functions, which deteriorates the operability. EP-A2-0844777 discloses a portable telephone with a single multi-functional key positioned near the display. The function of the key changes with mode change of the telephone and an appropriate symbol indicating the function of the key is displayed nearby. EP-A2-0679003, EP-A1-1004957 and US-A-5,737,394 all disclose portable telephones which include so-called soft keys. The function of the soft keys, of which there are usually three, changes according to the mode of the telephone and the current function of the key is indicated by a symbol displayed on the main telephone display, but nearby the relevant soft key. The pre-characterising portion of claim 1 is based on the disclosure of EP 0679003. In view of the foregoing, an object of this invention is to provide a portable telephone which can execute a desired function with simple operations. According to the present invention there is provided a portable telephone for executing various functions selected from hierarchically structured menus, comprising: assignable execution keys for instructing the execution of assigned ones of said functions; function assigning means for assigning to said assignable execution keys functions from those in said hierarchically structured menus; and function executing means for executing said function assigned to said assignable execution keys in response to the pressing of the assignable execution keys; characterised in that:- the function assigning means assigns to each said assignable execution keys a function selected by the user from those available in said hierarchically structured means. Functions selected by a user from hierarchically structured menus are assigned to dedicated execution keys and the functions, which are assigned to the execution keys, are executed in response to the pressing of the execution keys, so that the functions can be executed with simple operations, regardless of the hierarchies which the functions are belong to. Further, in the present invention, execution keys are provided next to a display means for displaying various information, and symbols representing the functions assigned to the execution keys are displayed next to the execution keys, which allows a user to easily and correctly recognize the functions assigned to the execution keys.

(5) Operations and Effects of Embodiment In the aforementioned configuration, in the portable telephone 1, when the 5D jog dial 10 is operated by the jog back operation while the waiting screen 100 is displayed on the display 5, the short-cut menu screen 130 is displayed on the display 5 accordingly. In the portable telephone 1, when the 5D jog dial 10 is operated by the jog back operation while the short-cut menu screen 130 is displayed on the display 5, the short-cut setting window 140 is displayed accordingly. Then, in the portable telephone 1, when "add item" is selected on the short-cut setting window 140, the main menu item selection screen 150 is displayed accordingly. And when the 5D jog dial 10 is operated by the jog pressing operation while the main menu item selection screen 150 is displayed, the sub menu item selection screen 160 is displayed accordingly. Then, when the 5D jog dial 10 is operated by the jog back operation while the main menu item selection screen 150 or the sub menu item selection screen 160 is displayed, the main menu item 200 or the sub menu item 210 selected on the selection screen is registered as the short-cut item. Then, in the portable telephone 1, the short-cut icons 103 showing the registered short-cut items are displayed on the waiting screen 100 above the corresponding user keys 9. As described above, in the portable telephone 1, both the main menu items 200 which are higher hierarchical items obtained by roughly gathering the items of the portable telephone 1 and the sub menu items 210 which are lower hierarchical items belonged to the corresponding main menu items can be equally registered as the short-cut items. Further, in the portable telephone 1, the short-cut icons 103 showing the registered short-cut items are displayed on the waiting screen 100 above the corresponding user keys 9, which allows a user to correctly recognize the short-cut items assigned to the user keys 9. Then, when a user key 9 is pressed by a user, the portable telephone 1 executes the short-cut item assigned to the user key 9. Thus, in the portable telephone 1, if items that the user often uses are registered as the short-cut items, the items can be easily executed by pressing the user key 9 only once, regardless of whether the item is the main menu item 200 or the sub menu item 210. Further, in the portable telephone 1, since the short-cut items are directly executed in response to the pressing of the user keys 9, the operation time to execute items can be shortened as compared with the case where the hierarchically structured menu screens are changed and a desired item is selected and executed. Thereby, the communicable time of the portable telephone 1 can lengthen by effectively using the limited capacity of the battery. According to the above configuration, in the portable telephone 1, the main menu items 200 or the sub menu items 210 desired by the user are registered as the short-cut items and the short-cut icons 103 showing the short-cut items are displayed on the waiting screen 100 corresponding to the user keys 9. Thereby, the short-cut items can be easily executed by pressing only the user keys 9. Further, since the portable telephone 1 is provided with the 5D jog dial 10 which can be manipulated in the five directions, the short-cut items can be easily executed, registered, and deleted by manipulating only the 5D jog dial 10. (6) Other embodiments Note that, the aforementioned embodiment has described the case of executing, registering and deleting the short-cut items by using the 5D jog dial 10.
