Mio P350 - Manual (Page 18)

If you are used to computer keyboards, you may consider trying one of the
QWERTY-type keypads.
3.2.6.2 QWERTY-type keyboards
QWERTY-type keyboards have both letters and numbers on them. Their layout is the
same as of the standard QWERTY and AZERTY (French) keyboards. To switch to
your desired QWERTY-type keyboard, press the Keys button.
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.
