[android-studio] How to increase editor font size?

I have the latest version of Android Studio installed (3.6.1).

I navigated to: File->Settings->Editor->Font. The dialog displays a warning message (yellow triangle) indicating that the Font is defined in the color scheme.

(Editing the Font here had no effect.)

Editor Font

I clicked on the dialog's warning message link.

This navigated to: File->Settings->Editor->Color Scheme->Color Scheme Font.

(Now I could edit the Font for my current scheme.)
