Where is the description?

Ladies and Gentlemen. I am very glad that I became a user of the GSE, but I would like to write something of my own. Where can I find the designation of all variables that are used in macros? such as “/ targetenemy [noharm] [dead]” I have no idea what this string means, but I would like to know …

I have seen this resource, but it is important for me to understand how the addon works and what variables can be used and for what purpose … So this is not quite what you need.
