Steps to reproduce:

1. Write this code:
        static void Main(string[] args)
        {
            //Create the data source
            List<int> Scores = new List<int>() { 97, 92, 81, 60 };

            // Create the query.
            IEnumerable<int> queryHighScores =
                from score in Scores
                where score > 80
                select score;

            var select = 0;
            // Execute the query.
            foreach (int i in queryHighScores)
            {
                Console.Write(i + " ");
                select = i;
            }
       }

Current results:
The keyword "select" is always highlighted.

Expected results:
The keyword "select" should only be highlighted once.
