k Template Input and Line Input
ClassPad supports two different input methods: template input and line input. Template input lets you input
fractions, powers, and other functions using formats that are the same as those in textbooks. Line input uses a
linear format for inputting expressions.

u Switching between Template Input and Line Input
Tap the L key. Each toggles the key color between white (L) and light blue ( ).
A white key indicates the template input mode, while a light blue key indicates the line input mode.
In the template input mode, you can perform template input using keys with

or

marked on their key tops,
such as N and !. Other keys input the same functions or commands as they do in the line mode.
Example 1: To use the template input mode to input
1. Tap the [Math1] tab and then enter the template input mode (white L key).
