   * Keys are typeset in **bold**   * 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). +  * 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).

-  * Special ​keys with long names are: **ALPHA**, **ON**, **SPC**, and **ENTER**. +  * The basic arithmetic ​keys are referred to as: **DIV** = divide (also **Z**), **MUL** = multiply, **SUB** = subtraction,​ **ADD** = addition  
-  * The keypad arrow keys are referred to by: **LA** = left keypad arrow, **RA** = right keypad arrow, **UA** = up keypad arrow, **DA** = down keypad arrow.+  * 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 shifted keys are **LS** = left shift and **RS** = right shift.
