-  * Number keys are referred to by their number (**1****2****3**, etc.), and similarly for the basic arithmetic operations of **x**, **-**, **+**. +
-  * Special keys with long names are: **ALPHA****ON**, and **ENTER**. +
-  * 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 shifted keys are **LS** = left shift and **RS** = right shift. +
-  * The backspace key (also labeled '​DEL'​ and '​CLEAR'​) is **BS**.+
  
-In order to reference a series of keys to be pressed in succession, a dash (**-**) will separate the keys.  Furthermore,​ since some key combinations require holding a key while pressing another, this is denoted by a superscript <​sup>​**hold**</​sup>​.+  * 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,​ **ADD** = addition; 
 +  * 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,​ since some key combinations require holding a key while pressing another, this action ​is denoted by a superscript <​sup>​**hold**</​sup>​.
  
 Here are some example key combinations:​ 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,+**LS-N** = left shift key followed by the **N** key, which on the keyboard refers to the **PRG** menu

 +Variables, commands, objects or anything that is presented "as shown on the calculator screen",​ are highlighted in red, like this: ''​VAR''​.

 +====RPL code====
  
-**RS<​sup>​hold</​sup>​-A** = while holding right shift key, press the 'A' ​key,+Reverse Polish List (RPL) code on the HP50g is understood as such when enclosed using the chevrons ​''​« »''​. ​ Within this documentall such code examples are highlighted. ​ So, for example, a RPL program to multiply the two numbers 24 and 42 would be shown like this:
