• Normally the input cursor appears as a straight vertical (I) or horizontal ( ) flashing line on the display screen. When there are 10 or fewer bytes of input remaining in the current expression, the cursor changes shape to I to let you know. If the I cursor appears, terminate the expression at a convenient point and calculate the result. k Correcting an Expression This section explains how to correct an expression as you are inputting it. The procedure you should use depends on whether you have insert or overwrite selected as the input mode. About the Insert and Overwrite Input Modes With the insert mode, the displayed characters shift to the left to make room when you input a new character. With the overwrite mode, any new character you input replaces the character at the current cursor position.The initial default input mode is insert.You can change to the overwrite mode when you need it. • The cursor is a vertical flashing line (I) when the insert mode is selected. The cursor is a horizontal flashing line ( ) when the overwrite mode is selected. • The initial default for Linear format input is the insert mode. You can switch to the overwrite mode by pressing 1Y(INS). • With Math format, you can only use the insert mode. Pressing 1Y(INS) when the Math format is selected does not switch to the overwrite mode. See "Incorporating a Value into a Function" for more information. • The calculator automatically changes to the insert mode whenever you change the input/output format from Linear to Math.
