 Selecting “Form” (formula) causes a formula in the cell to be displayed as a formula. The 
“Form” does not affect any non-formula data in the cell. 
 *
2
 Specifies the direction the cell cursor moves when you press the w key to register cell 
input, when the Sequence command generates a number table, and when you recall data 
from List memory.
