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
As an example, the functions associated with the equals key, 4, are illustrated in the text 
as follows: 
• primary function (equals): 4
• secondary function (display): \5
• tertiary function (random): ]6
