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). In this document, the following conventions are used when referring to various key press combinations:
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 hold.
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.
RShold-A = while holding right shift key, press the A key.
ONhold-Ahold-C = press and hold the ON key, then press and hold the A key, and finally press the C key.
Variables, commands, objects or anything that is presented “as shown on the calculator screen”, are highlighted in red, like this: VAR

Reverse Polish List (RPL) code on the HP50g is understood as such when enclosed using the chevrons « »
. Within this document, all such code examples are highlighted. So, for example, a RPL program to multiply the two numbers 24 and 42 would be shown like this:
« 24 42 * »
