Text Toolbar Missing

Hi. I am trying to enter chord names and have the extension as a superscript. I can't locate the text toolbar that used to be on the bottom left. I am trying to recreate a piece of music as an assessment and am not able to use the jazz font for the chord symbols as that would not be the same as the original. How do I now achieve this? Each time I try and do it in the inspector panel, the whole chord name moves up or down. Many thanks in advance for any help.
