Hit the CSS button on the far left of the Properties Window, as Nancy says. Go to Window > Properties or Ctrl + F3 if it's not open. That will give you your alignment and font formatting (aside from Italic and Bold under the HTML button in the same window).

Personally, I would recommend against using those formatting functions unless you're making an html email. By default, they create inline css which isn't as flexible as placing your css formatting in an external .css file using the CSS Designer, or just hand-coding the styles into your sheet.
