How the EquationWriter Application Is

Organized

In the EquationWriter application, keys corresponding to algebraic

functions enter the function name or graphical function symbol into

the equation. For example, pressing

(7^

draws a square root sign.

You can display any command menu—however, only those keys that

correspond to algebraic functions are active. Like the function keys

on the keyboard, the menu keys don’t execute the corresponding
function—they simply enter the function name into the equation.

The EquationWriter application consists of three modes, each with a

special purpose:

■ Entry mode—for entering and editing equations
m Scrolling mode—for viewing large equations
■ Selection mode—for editing expressions within equations
