System Events application process Acrobat

I found a script to manipulate Adobe Acrobat that is this:

tell application “System Events”
tell application process “Acrobat”

(stuff to do)

end tell
end tell

Where do I find a Dictionary for "“application process “Acrobat”” so I can view available commands?
Is this process “Acrobat” something the user had to create himself, or is there a reference somewhere?

That’s how you script the interface of Acrobat the application. You try to manipulate the windows and widgets directly. Have a look at the Precesses Suite of System
