Hi gang,

SC *2.4.5 
<https://sites.google.com/site/wcag2ict/home/2-operable/24-provide-ways-to-help-users-navigate-find-content-and-determine-where-they-are/245-multiple-ways>**Multiple 
Ways *was not one we reached consensus on.  Nor have we had much 
discussion on it thus far.

My thoughts on that can be found at the Applying UI Context 
<https://sites.google.com/site/wcag2ict/cross-cutting-issues-and-notes/user-interface-context/applying-ui-context> 
page in the fifth row, but to facilitate discussion, I reiterate them here.

The software portion of the UIC Proposal is:

    For software this applies directly as written and as described in 
    INTENT  from Understanding WCAG 2.0  (above) with the word "user
    interface context" substituted for Web Page  and "software program"
    substituted for "set of web pages".

    NOTE:  In the Understanding WCAG 2.0 writeup for this success
    criterion the WCAG Working Group gives examples of browsing and
    search as two possible methods for locating a Web page within a set
    of Web pages.  Both of these approaches would appear to be supported
    by most Electronic Documents,  and browsing and searching of help
    functions would appear to allow locating major sections in software
    as well.

    Note: Modal dialog boxes by their nature are considered part of a
    process that you can not navigate away from and must completed or
    cancelled before continuing.

I don't see how one locates a "set of user interface elements" within a 
"software program".  This set could be not a single window but a 
collection of windows; such collections aren't generally named entities 
one can navigate to as a collection.  This ties into my concerns with 
2.4.2 about what is a title of such a collection of windows.

Fundamentally I believe this SC doesn't really apply to software, and I 
think the right thing to do is go back to WCAG and see if we have their 
blessing to say exactly that.
