About the letter ō

ō is Unicode U+014D, named LATIN SMALL LETTER O WITH MACRON. It is used in Mandarin Pinyin, Māori and Hawaiian. A flat bar above a vowel, used for long vowels in Latvian, Lithuanian, Māori, Hawaiian and Latin textbooks, and for the first tone in Pinyin. See the ō character page for every code and shortcut.

If holding a key repeats the letter, press-and-hold is off. Turn it back on with the Terminal command above.
Option shortcuts depend on the keyboard layout. They work on US and ABC; other layouts move them.
If Option+E shows a highlighted ´ but no letter appears, you pressed a letter that cannot take that accent.
