To make corrections:

o      Use the DELETE key or BACKSPACE keys to remove text a character at a time.

o      To delete more than one character at a time, first select the text to be deleted and then press the DELETE key or BACKSPACE keys.

o      To replace or 'type over' text, make sure the Letter Writer is in over type mode (by pressing the INSERT key). Every character that is typed replaces an existing character to the Right of the text cursor. Press the Insert key again to return to insert mode.

o      To replace a block of text, first select the text to be replaced and then type the replacement text.
