Introduction
This document intends to trace the guidelines of a User Interface (in short: UI) for editing bidirectional (in short: Bidi) text. It is assumed that the user enters text in logical sequence, and that the Unicode Bidi Algorithm (in short: UBA) is used to reorder the text for presentation. We assume that the readers of this document have a working knowledge of the UBA. The UBA is described in Unicode Technical Report 9 (see http://www.unicode.org/unicode/reports/tr9).
When designing these guidelines, the following objectives were set, in order of decreasing priority:
- Prevent actions unexpected by the user, particularly when the action is destructive (erases one or more characters).
- Make the interface efficient.
- Keep the interface easy to implement.
