Here we can specify the standard and custom buttons that the related list displays. The Update Status button we just created should appear in the Available Buttons list.

Note
We’re not going to enable this Visualforce page for Salesforce mobile apps. Since Salesforce1’s related lists don’t display buttons, our users won’t be able to access the Mass Update Status page from a mobile device.

Once that's done, the Mass Update Status feature is ready to test!
