sets

Initial

key set

Secondary

key set

To switch between key sets, use the ↑ and ↓ arrow keys (see Figure 4.4):

• Pick the up (↑) arrow key to switch from the initial key set to the

secondary key set.

• Pick the down (↓) arrow key to switch back to the initial key set.

The initial key set contains all of the available operand keys, along with

various operator keys, the numeric keys, and the edit/control keys. Each of

these key types is discussed in later sections in this chapter.

The secondary key set offers additional operator types, replacing the initial

operands and some of the operators. It retains some of the initial keys,

including the numeric keys, the arithmetic keys, and the edit/control keys.
