[Tkinter] enter data with keypad

[Larz60+]

The .keysym_num column shows a numeric code equivalent to the key symbol. Unlike .keycode, these codes are different for different modifiers. For example, the digit 2 on the numeric keypad (key symbol KP_2) and the down arrow on the numeric keypad (key symbol KP_Down) have the same key code (88), but different .keysym_num values (65433 and 65458, respectively).
