is there a command in ruby that shows the whole list of texts available in
the app? $query("label",:text)

This is my first posting in stackoverflow.
First of all, I would like to say, I spent a very good amount of time to
research my question, but weren't there on any websites and ended up
signing up and post here.
I am very new to ruby.
The command $query("label",:text) filters out and shows every text
accessible on the current screen.
But, is there a command that shows the whole list of texts available in
the whole app instead of manually go through every screen?
Thank you.
