Shift Keys
Most keys on the HP 10bII+ have three functions:
• a primary function printed in white on the key.
• a secondary function printed in orange on the bevel of the key.
• a tertiary function printed in blue above the key on the keyboard (see Figure 1).

functions require subsequent key presses to operate. For example, the functions associated
