At the moment, the sub header navigation moves one section header at a time when using the < or >. We would like to change this so the > takes you to the next page worth of menu options, not just one section header.  
 
So for example, as the moment, on a device that shows 3 headers in the sub header, it takes 4 taps of the > to find search. By the > tabbing by page instead, it would take 2 taps. 
 
This improvement can help people who are using accessibility mode (voice over or talkback) because they can not wipe left/right on the sub header navigation.
 
When viewing a course page with more tabs than display on the page, pressing > should move one "page" of tabs, so if you can see 3 tabs, you should see the next 3.  Pressing < should move to the previous 3.
 
If there are not enough tabs to move a full page, you should move as far as the first or last tab, depending on the direction you are moving.
