Yes this is a very good point - let me clarify - I was thinking along the lines of the standard and non standard keys mentioned and that the documentation point is covered in principle 5 (I think). So, do you not think we could modify this to say: 4.1.3 No Keyboard Trap: If focus can be moved to a component with the keyboard, then focus can be moved away from that component using the same key combinations which enabled the focus or by follow appropriate operating system conventions. In both cases conformance to Principle 5.3. is mandatory. Is there not a better way to say this without the UI/Content distinction? Also, do you think the the AA level suggested means that developers will have more problems implementing this aspect? >>> A: No Keyboard Trap (Minimum): The user agent prevents keyboard >>> traps as follows: >>> (a) in the UI: if keyboard focus can be moved to a component >>> using the keyboard, then focus can be moved away from that >>> component using standard sequential keyboard commands (e.g., TAB >>> key) >>> (b) in the rendered content: provides a documented direct >>> keyboard command that will always restore keyboard focus to a >>> known location (e.g., the address bar). >>> >>> AA: No Keyboard Trap (Enhanced): In the rendered content, if >>> keyboard focus can be moved to a component using the keyboard, >>> then focus can be moved away from that component using standard >>> sequential keyboard commands (e.g., TAB key). >>> Cheers Si. ==== Simon Harper University of Manchester (UK) Human Centred Web Lab: http://hcw.cs.manchester.ac.uk My Site: http://hcw.cs.manchester.ac.uk/people/harper/ My Diary (iCal): http://hcw.cs.manchester.ac.uk/diaries/SimonHarper.ics +----------------------[ NEW & INTERESTING ]--------------------------------------+ ASSETS 2008 . 13-15 Oct 2008 . http:// www.sigaccess.org/assets08 +----------------------------------------------------------------------- ----------+
