If multiple entries share the same timestamp, the cursor moves to the entry on the lowest channel number. If no entry matches exactly, the cursor moves to the closest timestamp that does not exceed the specified value. When the specified timestamp is larger than the last entry in the display, the following dialog appears and the cursor does not move.
