How do you change the font on the first page when you first go into inbox?

How do you change the font on the first page when you first go into inbox? Don’t know what the page is called or how to do screen shots. Anyway, I found how I can change font of messages, but not the list of emails that are on that first page

You can find that setting in Menu > Tools > Settings > Appearance > Lists.

Yes, that is where I changed them for the messages, but it did not work for the first page where your list of emails are. 

Those settings I gave above are for the message list (1). The sidebar (2) cannot be changed. The message body (3) may be changed for plain text messages only, but that is another setting.

Awesome!  Thank you!  I will go try it.
