The syntax and formatting of the codex is a little confusing to me. Can someone help me learn what the different keywords mean. I get that "inseration" is an operator inserting a note into the file after it was written, but what are the "@" symbols used for? Or the keyword "query"? Or anything else I just haven't encountered yet?
Thanks in advance!
Edit: not related to original question, but what is "INDEX"? They refer to it in almost every file but I can't figure out what it is.
