What's the word or phrase for "reading strategy/orientation"?

Question

In English, we read from left-to-right, top-to-bottom.In traditional Japanese, text is read up-todown, right-to-left.Is there an English word that describes the "reading strategy" of a particular culture or language? Printers can be configured with "page orientation" for either "Portrait" or "Landscape", so perhaps something like "*reading orientation*"?---

tl;dr

The accepted answer, plus Java's concept of [text directionality](https://docs.oracle.com/javase/7/docs/api/java/lang/Character.html#getDirectionality(char)) inspires me to believe **directionality** is the most appropriate word here.

Answer 1

I performed an Internet search, finding 'writing direction', patterning, writing mode (on WWW, the World-Wide Web), and 2 directional orientations of Japanese writing terminologies. Directionality sounds good to me. Here are two sites to study further:
