Editing and Correcting an Equation

Cursor keys

Incorrect keystrokes can be changed by using the cursor keys

(l r u d).

Example

Enter 123456 then correct it to 123459.

1. Press j 123456.

2. Press y 9 e.

• If the cursor is located at the right end

of an equation, the y key will

function as a backspace key.

•You can return to the equation just after

getting an answer by pressing the cursor keys. After returning to the

equation, the following operations are useful;

@ l or @ r: To jump the cursor to the beginning or the

end of equation.

Overwrite mode and insert mode

• Pressing @ O switches between the two editing modes: overwrite

mode (default); and insert mode. A rectangular cursor indicates preexisting

data will be overwritten as you make entries, while a triangular cursor

indicates that an entry will be inserted at the cursor.

• In the overwrite mode, data under the cursor will be overwritten by the

number you enter. To insert a number in the insert mode, move the cursor

to the place immediately after where you wish to insert, then make the

desired entry.

• The mode set will be retained until @ O is pressed or a RESET

operation is performed.
