The keyboard has 3 distinct areas:

• Soft menu keys
• Commands and functions area
• Calculator pad

There's also 3 shift keys: left shift (arrow pointing to the left, from here on referred to as LS), right shift (arrow pointing right, from here on referred to as RS), and Alpha. Each shift activates different actions on the keys (typically painted the same color as the shift). Alpha enables alphanumeric mode in which text can be typed on the keyboard. Most keys have various letters and symbols associated to them in alphanumeric mode, depending on the shifts.

The top 6 keys (A through F) operate on the corresponding item on the top row of the on-screen menu (Menu 1). The 6 keys G through L operate on the second and third rows of the menu (Menu2). Hint: the position of the items on the screen resembles the position of the keys on the keyboard.

There is 3 rows of keys with various functions. Most keys work just as expected per the functions painted on them. Some keys have a new behavior, however. Some of the most important keys are M, which has the STO/RCL functions relocated since the K key is now part of the menu 2 keys, and the P key presents the main menu on the currently active menu (see menus).

These keys work for the most part as expected and are used mostly during numerical calculations.
