Yáʼátʼééh! I am using Multiling Keyboard for Android to type in Navajo, and it is very easy. I can type words beginning with Ł, and I have learned how to type numbers as dį́į́ʼ, four, but still I am not sure if it is the same as I can read in different sites. For example, in Wiktionary.
Yáʼátʼééh! I think the apostrophe is a right curve quotation mark. When I use the Navajo keyboard, the quotation marks are ' ', " ", and the apostrophe is ʼ. When I use the Hindi or English keyboard, for example, the quotation marks are very different, “ ”, ‘ ’, « », ˝ ˝, ' ', " ".
