I imagine there is already a keyboard out there (not sure how to search through the hundreds of keyboards available) that has special characters that include the cedilla on every (English) vowel letter, and the acute mark on every vowel letter, AND both acute mark and cedilla on every vowel letter. AND it needs to have the same two features (one or the other or both) for all the CAPITAL vowel letters as well.
Even if you have a hint for me for going about looking for that same keyboard, among all the hundreds available, I’d appreciate hearing from you. Thanks!
All vowels and all vowels with acute mark: a e i o u ó é and etc.
Upper case, too: A E I O U Ó É and etc.
Nasal Vowels: (with cedilla) ą Ą ę Ę į Į ǫ Ǫ ų Ų
Both marks together are also needed: é plus ̨ = ę́
É plus ̨ = Ę́
ó plus ̨ = ǫ́
Ó plus ̨ = Ǫ́
