Ovation Pro's algorithm for choosing variants may be simple but it doesn't
seem to be applied consistently. With font System ( Fixed / Medium ), if I
select some text and choose System from the top level menu, the text is
changed to System.Fixed. If I click on B, the selection changes to
System.Medium but if I then click on N, it stays as System.Medium - so N
doesn't revert to the default variant.
Font Hull ( Black / Black.Oblique / Light / Light.Oblique ) is even more
perplexing in that although the default is Hull.Black, the B and N buttons
both yield Hull.Light. Just to add to the confusion, B+I and N+I both yield
Hull.Black.Oblique!
Interestingly, Bookmark ( Demi / Demi.Italic / Light / Light.Italic ) which
seems to have its variants named similarly (except for Oblique vs Italic)
behaves exactly as one would expect - default and N give Bookmark.Light
while B gives Bookmark.Demi and the I button gives the corresponding Italic
variants.
It appears that the algorithm is not quite so simple - has it been tweaked
to accommodate some particular fonts to try to make it appear more
intelligent than it really is?
