If you have Arabic or Hebrew content embedded in LTR text, Arbortext Editor automatically detects the RTL text and moves the cursor appropriately when you are using the arrow keys to move through a document. The reverse also holds true, so Arbortext Editor moves the cursor appropriately when it encounters LTR text embedded in RTL text. If you are selecting text that has mixed content with the arrow keys, Arbortext Editor moves the point of selection appropriately for LTR and RTL text selections. However, if you are selecting text with the pointing device, Arbortext Editor selects the entire embedded reversed content when the point of selection encounters text that has different directionality from the surrounding text.

By default, Arbortext Editor handles text with mixed directionality in this way regardless of the current document or element directionality. The set caretmovement command enables you to control how the cursor moves through text with mixed directionality.
