How to type a macron over a consonant?
I need to type in the Motu language, which has two distinct 'g's, and in their orthography, one of them is represented by 'g' with a macron over it.
How can I type a macron over a consonant repeatedly, without constantly bringing up the Emoji & Symbols menu? Note, I did create a shortcut in Settings/Keyboard, but that ONLY works if I employ my shortcut at the beginning of a word. Annoyingly, it will not work if I use my shortcut anywhere else in the word. To do so, I have to type the word in pieces, with the shortcut beginning each piece, then backspace the pieces to join them up. This is not my idea of a shortcut. I want to be able to quickly type the 'macron g' anywhere I want. Surely this is possible?
