MacOS – Automatically change settings of Terminal when in full screen

fullscreenmacosterminal

I often use emacs from a terminal (emacs -nw), and when comparing two files side-by-side (C-x 3) it is often useful to go into full-screen mode. I'm using a 27" screen, so full-screen mode provides a lot of screen real estate, usually more than I need. To counteract this, I typically increase the font size under Terminal->Preferences->Setings.

Is there a way to have settings — e.g. font size — changed automatically when going to full screen in a Terminal application?

I notice that one can define a preset Setting, which can be swapped out easily, but it would be nice if it was swapped out automatically when going full screen.

You could try AppleScript to do something like

tell application "Terminal"
    set zoomed of window 0 to true
    set font size of window 0 to 24
end tell

but I haven't found a way to activate fullscreen mode this way yet
