Game Data (Control Variables) Script Commands?

1) Is there a list of the script commands for each of the game data options under control variables, such as item possession count, etc?

2) Or even beyond what control variables offer? Having a list of most, if not all, of these ($gameParty, $gameActor, .numItems, etc) script commands available to us.

I've found some of them on my own over time, but when I need to refresh myself how to do one of them, I have to seek out instances where I've utilised it, and it would be faster if there was one location to quickly reference. And especially with respect to my first question, I am FULLY aware of the existence of the google spreadsheet.
