shifts up and the equation editor menu is displayed as the
lower menu. You can store up to 99 functions in the
equation editor, if sufficient memory is available.
If a function is selected, its equals sign (=) is highlighted in the equation editor. If the
function is deselected, its equals sign is not highlighted. Only selected functions are plotted
