+ | ====Keys==== | ||
+ | The HP50g has a total of 51 keys, most of which have multiple functions that can be activated with a modifier key (left shift, right shift, or ALPHA). | ||
+ | |||
+ | * keys are typeset in **bold**; | ||
+ | * the majority of keys will be referred to by their alphanumeric label (**A** through **Z**), unless it makes sense by context to refer to another label on the key (for example, when referring to trigonometric functions, the **S**, **T**, and **U** keys may be referred to by their function names **SIN**, **COS**, and **TAN**, respectively); | ||
+ | * number keys are referred to by their number (**0** through **9** and the decimal dot, **DOT**); | ||
+ | * the basic arithmetic keys are referred to as: **DIV** = divide (also **Z**), **MUL** = multiply, **SUB** = subtraction, | ||
+ | * the special keys: **AL** (ALPHA), **ON**, **SP** (SPC), and **EN** (ENTER); | ||
+ | * the keypad arrow keys are referred to by: **LF** = left keypad arrow, **RT** = right keypad arrow, **UP** = up keypad arrow, **DN** = down keypad arrow; | ||
+ | * the shifted keys are **LS** = left shift and **RS** = right shift; | ||
+ | * the backspace key (also labeled **DEL** and **CLEAR**) is **BK**. | ||
+ | |||
+ | In order to reference a series of keys to be pressed in succession, a dash (**-**) will separate the keys. Furthermore, | ||
+ | |||
+ | Here are some example key combinations: | ||
+ | |||
+ | **LS-N** = left shift key followed by the **N** key, which on the keyboard refers to the **PRG** menu. | ||
