Comment 0 for bug 1265089

In pages such as /admin/users/staff.php and /admin/users/admins.php, staff or administrators are chosen by selecting items in one list then clicking a button to transfer them to another list. However, the buttons do not have a descriptive value so it's hard for screen reader users to figure out how this works.
The "<" and ">" buttons should be given values which describe what they do (eg. "Move to administrators") and a note should be added in the user manual which explains how to select and move items using the keyboard (including selecting multiple items, etc.)
