Rundown on gcloud – syntax clarification

I’m reviewing the lesson for gcloud.  I understand the syntax goes from left to right indicating:

 gcloud [global-flag] [services/prod] [command] [flags] [parameter].

the mandatory commands are ‘gcloud [services/prod] [command] and all others optional or if required by the command string. Its not always obvious in a string what’s a global flag vs services vs command vs flags etc.. can i associate each word in the string by aligning the words in the syntax from right to left? this would be for commands that dont use the entire syntax of words available.

example: ‘gcloud config configurations list’

reading right to left  :  list [command] configurations [group] config [services/[prod]….. ?

thanks! -rg
