Seems cleaner to use the WCAG wording as Alex suggested.   I would not add
the additional text Jutta is suggesting as I believe it is  redundant to
the point of the topic.   But, I do think Jan's  suggestion is also a bit
more clear.   The problem is, it does address the documentation
requirement, but that should be covered through the requirement to document
all accessibility features and keyboard definitions.

Perhaps we can remove "of the page" and insert the words after components,
"including editing views that render content that may have keyboard traps"
and then use this text.
