how to change multiple rows in a table

I am using access directly. No code is being used. When I have a table open, how do I change the field of multiple rows.  I can select multiple rows, but cannot find a way to update a field for all those rows.  Example: Fields hello, color, istrue  Question: How would I set multiple rows color field to say, 12345.

Also, a nagging question. What do experts get out of answering these questions? Can you redeem your points for cash or some other product?  Just recognition?  Thanks.
