For all elements in the Design module that show text, the font can be edited.
Click in the right-hand column here if you want to change the font. Inherit means
that the font will be transferred to the text by the related parent element. You
can enter installed (or not installed) fonts here directly in the
selection list. You can also select installed fonts comfortably from a
dialog, which will be opened when you select the entry to Select font types.
