(D) to display the DISPLAY MODES input form. The Font: field is highlighted, and the option Ft8_0:system 8 is selected. This is the default value of the display font. Pressing the @CHOOSE soft menu key (B), will provide a list of available system fonts, as shown below:

The options available are three standard System Fonts (sizes 8, 7, and 6) and a Browse.. option. The latter will let you browse the calculator memory for additional fonts that you may have created or downloaded into the calculator.

Practice changing the display fonts to sizes 7 and 6. Press the OK soft menu key to effect the selection. When done with a font selection, press the @@@OK@@@

soft menu key to go back to the CALCULATOR MODES input form. To return to normal calculator display at this point, press the @@@OK@@@ soft menu key once more and see how the stack display change to accommodate the different font.

Selecting properties of the line editor

First, press the H button to activate the CALCULATOR MODES input form. Within the CALCULATOR MODES input form, press the @@DISP@ soft menu key (D) to display the DISPLAY MODES input form. Press the down arrow key, ˜, once, to get to the Edit line. This line shows three properties that can be modified. When these properties are selected (checked) the following effects are activated:

_Small	Changes font size to small
_Full page	Allows to place the cursor after the end of the line
_Indent	Auto indent cursor when entering a carriage return

Instructions on the use of the line editor are presented in Chapter 2 in this guide.
