While typing in my terminal, I discovered that the "b" key is no longer working. When I type the letter 'b', the terminal interprets it as the sequence of characters '"C": forward-word'. The 'b' key works correctly in other applications (e.g. as I type it to you now) and even capital 'B' works correctly in the terminal.
How can I get the terminal to correctly interpret this key? I haven't changed any settings recently, and to the best of my knowledge this key had been working correctly in the terminal since I got the computer about a month ago.
