When I click 'Type Tool', base font is 'Minion Pro'. I don't use this font very well.
So, I'd like to chane base font. How can I change it?
Do not have a document open, nor even a blank document.
Select the Type Tool.
Make your font selection.
When you restart, all new documents will have that chosen font as the default.
I would recommend to create a own basic paragraph style, when no document is open and select this style.
I would not recommend to work without any paragraph style anyway.
