Mio MIOMAP C220 - Manual (Page 13)

This type of keyboard has large, finger-friendly buttons.
Note: If you have chosen a program language that uses Latin letters, only the ABC
keyboard appears. If you choose the Greek language, an additional keyboard
appears with Greek letters. Similarly Hebraic and Cyrillic letters are available when
Hebrew or Russian is chosen in Setup / Languages (Page 78).
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.
