Changing fonts?
 

I've clicked on anything in "settings" and "rich text" that has to do with changing the font when composing an email and no matter what I do I still get the same font. I want to be able to change permanently to something different. What's the secret, please?

Settings/MAIL/Preferences
Writing/Default Style

Click on Font Face, a drop down menu gives you a choice of font, and shows you how it will look immediately below.

That works for me.

Thanks!
 

Thanks... that's one I missed. This new UI has more places to look for controls and adjustments than Classic did. I have what I needed now.
