Key Presses, the Shift Key, Secondary, and Tertiary Functions*

To execute the function associated with a key, press and release the desired key. However,
most of the calculators' keys have more than one function: the first, or primary function, the
shifted, or secondary function, and, in some cases, a third, or tertiary function (see Figure 2).
* Tertiary functions do not apply to the HP 20b.
