Does my Nokia device support full QWERTY keyboard on touch screen in addition to the physical QWERTY keyboard?

In devices with a physical QWERTY keyboard there is usually only an alphanumeric keypad available via the touch screen interface, for example in the following devices:

  • Nokia N97
  • Nokia N97 mini
  • Nokia C6-00

The full QWERTY keyboard is available in these models by sliding open the device.
