Two versions are provided for desktop:
1. Chatino provides capital letter tone marks A-L on the digits, and tone marks M-W on shifted digits.
2. The Alt-levels have digits and punctuation symbols.
3. The mobile keyboard includes accented characters and superscript tone marks as long press options on letters A-W. Note that superscripts for q and s are lower cases because the uppercase Q and S are not yet in the Unicode standard..
To use the keyboard, KeyMan software must first be installed on the computer or mobile device. Then the Chatino layouts can be installed.
This version was update in 2022 by Craig Cornelius from the 2020 version made with consultation with Emiliana Cruz.
