How to indicate word stress in a Latin word

Salvēte! Does anyone have a suggestion on how to indicate word stress in a Latin word that would work in Word, and html? I have played with both an underscore and a dot below the letter (see below). The diacritic would have to be able to be combined with a vowel with a macron. And be pleasing to the eye.

optātū̲rus optātụ̄rus optātū̪rus

On a Mac, I use Option-A plus “a” for the macron, and Ctrl-Cmd-Space, and choose “combining low line”, “combining dot below”, and “combining bridge below” for the other three diacritics.

I have not been able to find a combining acute accent like the one used in Wheelock as yet, but find it a bit busy with both a macron and an acute accent on the same vowel.

Hi, I don’t mark word accent (pitch in my view rather than solely stress, but that’s a different story), since the accenting rules are much simpler than Greek and you can read them on the fly, but if you’re going to invent symbols anyway, you could perhaps use something a little ‘lighter’, e.g. ã is accented long, ā unaccented long, á accented short.

Tĩtyre, tũ pátulae récubāns sub tégmine fãgī,

I’ll leave it to you though as to what looks best from your perspective - I don’t use this system (I just made it up as a suggestion for you); I just use macrons (using the Maori keyboard: hit the tilde button on the top left and any vowel, and you can insert macrons super fast while typing. It works on both Mac and PC and you don’t need any third party software, but just add another keyboard from the languages settings for Mac or PC; it works in the same way.)

You could bold the stresses letter, as many European Latin textbooks do.
