Cursor movement
This page explains how cursor movement behaves in the input fields when handling bidirectional (BIDI) text.
Logical Cursor Movement
Unity currently follows a Logical Cursor Movement approach. This means the cursor moves through BIDI text based on the direction of the segment of text. For example, using the left arrow key in a sentence with Arabic and English text, it moves right-to-left through Arabic, then jumps at the leftmost character in the English segment and continues left-to-right until it reaches the end of the segment.
Visual Cursor Movement
Some applications follow a Visual Cursor Movement approach. This means the cursor moves to the next visual character regardless of the direction of the text, which can sometimes feel more intuitive for users.
