Crafting
Crafting is best done with a small enlargement. It is better to select a dark background during

Writing
You can also write under your video magnifier. It is best to use a black pen and lined paper.
Readhelp

different from t he t ext. T he read help can only be act ivated in the negative and positive
reading mode.
