Inputting and Editing eActivity File Data

uInputting and Editing Text Line Contents

•You can input up to 255 bytes of text into a text line. Scroll arrows (]' the left and right sides of the text line to let you know there is additional fit within the text line display area. In this case, you can use the left and to scroll the text.

) will appear on text that does not right cursor keys

•The 5(A↔a) function key toggles between upper-case and lower-case input. This

function is available only during alpha input (page 1-1-3). The text line cursor is “” while upper-case input is selected, and “” during lower-case input.

•You can input a carriage return into a text line by pressing w. Note that there is no return display symbol.

•To clear all of the text in the text line where the cursor is located, press the A key.

kUsing Math Lines

A math line lets you input a calculation into an eActivity file, and then perform the same calculations you use in the RUN • MAT mode while “Math” is selected as the Input Mode. Math lines always have two parts: an input expression and a result.

eActivity calculations are different from RUN • MAT mode calculations as described below.

•When you input a mathematical expression into an eActivity, the Input Mode (page 1-3-8) always changes to “Math”, regardless of the calculator’s current input mode setting.

•You can input stop lines in an eActivity.

#When you input a mathematical expression into a text line, the Input Mode (page 1-3-8) always changes to “Math”, regardless of the calculator’s current input mode setting.

#Pressing 6(g)4(MATH) displays the MATH submenu. You can use this menu for natural input of matrices, differentials, integrals, etc. For details about input using the MATH menu, see “Using the MATH Menu” (page 1-3-10).

#Any mathematical expression you input into a text line is non-executable.
