You have scrambled your text here and didnít substitute or pull text properly -- which is why this looks scrambled to you.    But this is a closed item and lets not waste time on this now.

However, I thought it would be useful to look at it with the new UI Context definition, to help evaluate that definition and where we might use it.  My thoughts on this can be found at the Applying UI Context page in the fourth row, but to facilitate discussion, I reiterate them here.

While the consensus text arguably has a similar deficiency, I think it is more likely to be understood by readers as applying to a single window's UI, and not all of the windows (as constituting the "software interface").  Perhaps public comments on this consensus text will reveal any such potential concerns.
