Key Area
The formula entry keyboard enables you to select the various operands,
operators, and other elements that will make up the formula you are defining.
The keyboard has two main areas – the key area, and the display area (see
Figure 4.3).
Display area: The display area lists the formula name (which can be
user-assigned), and lists the formula components as you select them.
Key area: You pick the keys in the key area in order to select components
(operators and operands) to define the formula. The keys fall into several
general categories – operand keys, operator keys, numeric keys, edit keys,
and miscellaneous other keys.
Accessing the two key sets: The formula entry keyboard actually has two
different key sets, in order to accommodate all of the formula elements. You
can easily switch between the two key sets as necessary (see Figure 4.4).
