How to use same font for every file type in emeditor?

I found answer here: https://www.emeditor.org/en/faq_view_view_different_fonts.html

Q. Different fonts are used when opening different files, or the font used for a new file is different. How can I always use the same font?

Select "Properties for All Configurations" on the "Tools" menu, select the "Display" page, click the "Font" button, and the "Customize Font" dialog box appears. Click the "Select All" button, and click the "Change" button in the "Display Font" box, and select the font you want to use.
