a preceding " is acute accent
a following : is the macron
a following . is the syllabicity marker
h always becomes superscript and v is superscript w.
Palato-velars are marked with a following ' and x1, x2, x3 etc. yields the laryngeals, with x@ for the subscript a laryngeal, and xx for an unknown laryngeal.

There's probably more, but this is best learned by experimenting (or reading https://github.com/dali99/matrix-wug/blob/master/x2i/apie-keys.yaml)

Percentage sign after a vowel gives it both an ogonek and an acute accent: a% → ą́, I% → Į́ and after an l, it makes ł: l% → ł
You can also "stack the symbols" for an ogonek and an accute accent: (a^@, a@^) → ą́
Single quotation mark is converted to the glottal stop/ejective mark (’)
For a plain quotation mark, you can type '^
