	Table 1-2. Keys for Clearing
Key	Description
<	Backspace; erases the character before the cursor.
C	Clear; clears the calculator line. (When the calculator
	is off, this key turns the calculator on, but without
	clearing anything.)
@c	This clears all information in the current work area
	(menu). For example, it will erase all the numbers in
	a list if you are currently viewing a list (SUM or
	CFLO). In other menus (like TVM), @cclears
	all of the values that have been stored. In SOLVE, it
	can delete all equations.

The cursor (  ) is visible while you are keying in a number or doing a calculation. When the cursor is visible, pressing < deletes the last character you keyed in. When the cursor is not visible, pressing < erases the last number.
