Narrative:

Boids arrival 10 mi prior to siler. I was PF. Brought in at 12000 ft for traffic. About 10 mi prior to siler given a runway change to runway 35C. Entered in box but forgot to re-input arrival. Distraction by non standard altitude and 90 KT tailwind. Aircraft went into heading hold and I missed it. Shortly after siler arrival gave us a turn to 190 degrees. It was then that I noticed the heading mode. It is basic flying but on this day I did not confirm that what was on the FMA agreed with what was in the box. In the future I certainly will.
