The numeric keypad on the Platform works like the numeric keypad
displayed on the screen: push on a number to display it.
The numeric keypad of the Platform can also be used when the edition
keypad is displayed on the Platform screen.
– To enter exclusively numbers, select 123... with the key and
type the number(s) wished to display it/them.
– To enter letters and numbers, select abc2... with the key and
type as many times as necessary on a key of the numeric keypad of
the Platform to insert the character wished.
For example, to enter the letter «o», push three times the button
«6». If you click one again, you will display the number «6».
– Some specific characters (e.g. @, /...) can be entered using specific
keys from the Platform keypad:
