Do you mean to say that you are not pushing any keys and Pico
justifies text without request, or do you mean to say that you tried
to push Ctrl-W Ctrl-Y to go to the top of the file and by accident you
pushed Ctrl-W Ctrl-U to justify the full text? The latter can be
undone by pushing Ctrl-U right after the full justification.
Unfortunately, the full file justification can not be disabled. I
dislike it, and have been bitten by the same problem you've had
several times.
I hope this clarifies what is happening to you.
