Links for hiding/showing more content need accessibility info

[Robert Lyon]

Some links in Mahara are simply used to toggle the display of more information.
For example in the inbox or the my notes page.

For a screen reader user clicking on the link gives no feedback that new information has been displayed (or hidden) as no new page (or new content) is loaded.

There needs to be some accessible-hidden text that indicates what the link is actually doing.
