DefaultFont sets the default font to font fontname. The default font is used by fvwm whenever no other font has been specified. To reset the default font to the built-in default, omit the argument. The default font is used for menus, window titles, icon titles as well as the geometry feedback windows during a move or resize operation. To override the default font in a specific context, use the Style * Font, Style * IconFont, or MenuStyle commands.
