There are few fields that should be in ltr direction for convenience, as these fields only accepts English letters. Editing a template: the template name field. Editing a template modification: the template name and modification key fields. Editing a phrase: the phrase title field. Searching a phrase: the phrase title field. Editing user group: the "custom CSS class name" for user banner styling. Creating an addon: the addon id and the url fields. As well class::method fields. When installing or upgrading an addon: the field to write a path ("Install from file on server"). Display Criteria (for notices for example): All the Page Information fields (Navigation Tab, controller, view class, template) Editing Admin Navigation: the Admin Navigation ID field Creating property style: the Property Name field Possibly there are more, but these the main ones that I found.
