It’s no secret. I am no fan of Latin macrons. Silly stumbling blocks, in my opinion.
Still, more people use them than people who don’t use them. Well, as for those Latin teachers, I don’t know half of them half as well as I should like; and I like less than half of them half as well as they deserve. (Thanks, Bilbo.)
Nonetheless, if you do want to macron (though, why you would is a mystery to me) you now have some tools to do so. Thanks go to a Latin student who likes macrons more than I.
Here are a few links he recently donated to me. Happily, I donate them to others.
