+Subject: [PATCH] schemas: add a scroll button locking to the trackball
+
+Where enabled, the first click of the scroll button sets the button logically
+down, the second click sets the button logically up.
+
+This is an accessibility feature, it doesn't require users to keep holding the
+button down while scrolling which is hard or impossible for some users.
