Mio MioMap v3.3 C320 - Manual (Page 15)

The special keys described in the previous section are also available here.
3.2.6.3 The numeric keyboard
The numeric keyboard only contains numbers, on huge buttons. The special keys
you find on the other keyboards (except Space) are available here as well.
Although QWERTY-type keyboards also contain number keys, when entering a
house number, the program offers the more convenient numeric keypad.
