I have a notation that should consist of a header in all caps that I want centered, with several paragraphs below it that should be aligned left.  I can't seem to get it to work.  The notation is initially set up to be centered.  I type the header, then hit Enter and click on the button at the top for Align Left and the header moves to the left.  I tried typing all of it with the Align Left option selected and then went back and highlighted the header and clicked on the Centered button and everything moved to the center.  Am I missing something?  Is there no way to have the alignment affect only parts of a notation?
