Still chomping my way through 2.7 - here is sc 2.7.5 for your perusal, 
this SC already had text in it I'm just moving it into a form that is 
more in keeping with the others and polishing, or maybe tarnishing, it...

2.7.5 (former 4.7.1) Access to Relationships which Aid Navigation: The 
user can access explicitly-defined relationships based on the user's 
position in content, and the path of nodes leading from the root of any 
content hierarchy to that position. (Level AA).

Intent of Success Criterion 2.7.5 (former 4.7.1) :
Let the user use the keyboard to navigate forwards and backwards through 
elements that they are likely to be interested in interacting with. 
These elements must include, but are not limited to, enabled links and 
controls. This allows the user to jump between elements without having 
to navigate through intervening content such as blocks of text. 
Efficient keyboard navigation is especially important for people who 
cannot easily use a mouse. Efficient keyboard navigation aids structured 
navigation by enhancing a users comprehension of their position (e.g., 
show form control's label, show label's form control, show a cell's 
table headers, etc.).

Examples of Success Criterion 2.7.5 (former 4.7.1) :
Jane has mobility problems and cannot use the mouse to make direct link 
selections. She uses the keyboard for all her interaction with the 
system and instead of selecting links with the pointing device she uses 
the browsers built in sequential navigation system by pressing the Tab 
key to move the focus to the next link or control in the page, and press 
Shift+Tab to move in the reverse order.

Related Resources for Success Criterion 2.7.5 (former 4.7.1) :
See 2.1.4 for a discussion of letting the user configure the list of 
important elements to suit their task.
