I'm using a Nokia 5230 (S60 5th) device.It does not have a keypad.
When I start BluePad, it asks me to press 5. But with this device it is not a possible thing to do. Usually the on-screen keypad pops up only at a text/numeric input field.
I think this can be fixed if a key-binding is also made with the middle softkey (the key surrounded by the four scroll keys).
A screenshot is attached.
