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).
Figure 1
When you press \ or ], a shift annunciator or is displayed to indicate that the
shifted functions are active. For example, press \ followed by 2 to multiply a num-
ber in the display by itself. To turn the shift annunciators off, press \ or ] again.
Boxed Key Functions
There are three shifted key functions on the calculator that are used to change the operation
of another key's function. These three tertiary functions, ]O, ]o and
]r, are bound by blue boxes to show that they operate differently. These special
functions require subsequent key presses to operate. For example, the functions associated
with the clear key, M, include:
