Stylus input is a writing canvas setting in Skritter: Write Chinese and Write: Japanese. When it is enabled, Skritter will use pressure-sensitive data from an input device to make the squig look more nuanced and ink-like. It is most noticeable when used in conjunction with rawest squigs for a more natural, pen-and-paper style writing experience, but can be used in any writing mode.
How to Enable
Stylus input can be enabled in the Writing Canvas Settings section of the account study settings. It can also be found in the quick settings drawer on learn, test, and review modes. Stylus input can only be used with the default writing canvas. It is not supported by the basic writing canvas.
