Script Summary: Keyboard shortcut to sort feed based on unread items. Options : Key '3' : Sort on unread items, show only unread items. Key '4' : Sort on unread items, show all (read/unread). Key '5' : Restore original view. Similar to Shortcut Key 1/2.
1. Option to sort on Unread items.
2. Option to display selective items (unread/all).
3. Restore original view.
2. The feed sequence may go totally out of sync with the actual feed sequence after multiple reads and command execution. GR automatically downloads new entries as you move through feeds. Did not check the functionality if these keys works with that functionality. In either case, a refresh (or shortcut keys 1/2) should update the view to new items. Needs to be verified.
1. Default keyboard shortcuts to go up and down through feed do not work correctly. They still move based on the original entries sequence only.
