Guideline A.3.6: (For the authoring tool user interface) Manage preference settings. [Implementing A.3.6] Rationale: Some authors need to set their own display settings in a way that differs from the presentation that they want to define for the published web content. Providing the ability to save and reload sets of keyboard and display preference settings benefits authors who have needs that differ over time (e.g. due to fatigue). A.3.6.1 Independence of Display: If the authoring tool includes display settings for editing-views, then the authoring tool allows authors to adjust these settings without modifying the web content being edited. (Level A) Implementing A.3.6.1 A.3.6.2 Save Settings: If the authoring tool includes display and/or control settings, then these settings can be saved between authoring sessions. (Level AA) Implementing A.3.6.2 A.3.6.3 Apply Platform Settings: The authoring tool respects changes in platform display and control settings, unless authors select more specific display and control settings using the authoring tool.
