Expanding/Collapsing Text

From Help Wiki

After inserting a text box to your power point by clicking inside it you are now able to type. After any text has been entered you can now edit it by using the formatting palette. This floating window allows you to expand and collapse your text by using a scrollable list of text sizes as well as a sliding bar to the right of the word "size". Both of these tools can be used to expand and collapse your text.
