Different fonts and font sizes for composition mode

Is there a way I can have the Editor (i.e. the main screen that is usually beside the binder) have one font and font size and the fullscreen composition mode have a different font size and font?

I would like to do this because I use a 13 mbp plugged into an external monitor and I like the font bigger etc. on the larger external monitor.

You can’t have different fonts, but you can adjust the zoom/text scale.

Adjust the Text Scale inn composition mode; it’s in the slide-up toolbar on the bottom of the screen, all the way to the left.

In the regular screen view (full screen, or just regular windowed mode), if you have the footer visible, you can adjust the text zoom for the editor there. The two zooms are separate.
