AviatorCalc keyboard support

AviatorCalc works with the three standard keyboards:
There are at least three keypad or keyboard layouts used by mobile phones. These are:
 

• ITU-T keypad (for example Nokia 6220 classic)
• Half-QWERTY keyboard (for example Nokia E55)
• mini-QWERTY keyboard (for example Nokia N97)

The ITU-T keyboard is the most popular variant found on mobile phone. It has a 12 key alpha-numeric keypad. It is often used with predictive text entry. AviatorCalc was written primarily with this type of keyboard in mind.
	The half-QWERTY keyboard is found on several smart phones such as the Nokia E55. It typically has a 20 key keypad. There are two characters with a single numeric (Example 1,E and R). To display the alternative characters and numerics the shift key must be used. On the graphics screens in AviatorCalc the shift key must be used to enter numbers. Some phones do not make the shift key 'sticky' so it has to be pressed each time to enter a numeric. This makes it less easy for programs such as AviatorCalc which use the low level user interface on its graphics screens.
The mini-QWERTY keyboard is found on PDA's and smart phones such as the Nokia N97. It has a QWERTY keyboard but without the top row of numerics. The numbers are displayed on the keys Q through P on the top row. To display the uppercase characters and numerics the shift key must be used. On the graphics screens in AviatorCalc the shift key must be used to enter numbers.

Note: No testing has ever been carried out with a device using an AZERTY keyboard used primarily in France and Belgium. If you have such a device, download the Crosswind Demonstration program and let us know how you get on via the Feedback Form.
