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"?
The accepted answer, plus Java's concept of text directionality inspires me to believe directionality is the most appropriate word here.
