  or more songs can be moved to another saved station.
- A now announces the artist, replacing the old W command.
- W is unassigned.
- T announces the current song title.
- Ctrl+Up and Ctrl+Down do nothing in normal station lists.
- Shift+Up and Shift+Down do nothing in normal station lists.
- Shift+Up/Down remains available only in the Ctrl+S search-results list.
