In order to type Nisqually correctly on your Chromebook, you will need to download and install the Nisqually keyboard layout. This only needs to be done once on your machine – after that, you can switch between the English and Lakota keyboard layouts. With the Nisqually layout turned on, you can use your computer keyboard to type the unique Nisqually letters.
