Some contextual alternates are already implemented in the font and can be manually implemented by the users. Examples are kaf, gaf, be, te, fe and sin, and some elongated forms are also provided. [...]
How can we access these alternates? I found the swsh and jalt features, which activate the elongated forms; and ss01–ss04, which affect the positions of dots; but how can we enable the other shapes shown in the image above?
