Saving and canceling

The Save and Cancel functionality implemented at the end of a series of steps allows the
user to save the change or exit the function without saving any of the changes. The way
these functions are shown should always look as follows:
Saving
Whether you're choosing a setting from a list of choices or entering digits or text the first
screen shall show "SAVE?" to ask the user if they want to save the information just
entered. You can select the cancel function (choose NO) or the save function (choose
YES). After the save function is selected, "SAVED" shall appear on the screen.
