Example 2: To copy an expression you input with the Main application to the Graph Editor window
1. In the Main application work area, input: 2 x ^2 + 2 x − 1.
c2x{2+2x-1E
2. On the right end of the toolbar, tap the down arrow button. On the button
palette that appears, tap !.
• This will display the Graph Editor window in the bottom half of the screen.
3. Select the 2 x ^2 + 2 x − 1 expression you input with the Main application by
dragging across it, and then drag the expression to the located to the right
of
y 1: on the Graph Editor window.
• This will copy 2 x ^2 + 2 x − 1 to the location where you dropped it.
Tip
• An expression you copy using the operation above is registered to the Graph Editor
window of the Graph & Table application. For information about Graph Editor window
operations, see Chapter 3.
• Depending on the destination to which you drag a character string or an expression,
the drop operation may cause it to be converted automatically to a graph or a
figure. For example, dropping the expression in Example 2 into the Graph window will graph the expression. Refer to the
locations provided below to see examples using drag and drop.

Various Soft Keyboard Operations
This section explains how to use each of the soft keyboard key sets. For information about key set types and a
general overview of key sets, see “Soft Keyboard Key Sets” (page 16). All of the examples in this section assume
the following conditions.
• The Main application is running. See “Built-in Applications” (page 12).
• The soft keyboard is displayed. See “Using the Soft Keyboard” (page 15).
k Using Math, Trig, and Advance Key Sets
The [Math1], [Math2], [Math3], [Trig] (trigonometric), and [Advance] key sets
contain keys for inputting numeric expressions.
The
L key in the upper left corner and all of the keys in the bottom row are
common to all key sets. Their functions are described below.
L Switches between template input and line input. See “Template Input
and Line Input” (page 22).
h Performs the same operation as the keypad’s K key. Deletes the
character to the left of the current cursor position.
pq See “Using the Clipboard for Copy and Paste” (page 19).
D Inputs “ans”. See “Using the Answer Variable (ans)” (page 43).
w Performs the same operation as the keypad’s E key, which executes calculations.
