Question Writer Manual/Quiz Options/Text Settings/Title Text Font
Title Text Font
If you are using the Standard version of Question Writer 4, these options (apart from the Override Title Text Font Color) can be found in Quiz Properties - Appearance Settings.
Override Title Text Font
Each theme defines a different font to use in the quiz for titles - you can override that selection by choosing your own font here.
Override Title Text Font Size
As well as changing the font used you can also change the default font size for the titles. This could be useful eg if you want to display your quiz using an OHP and need to make sure everyone in the room can read the text.
Override Title Text Font Color
|Quiz authors using the Professional version also have the option to change the color of the title text.
