Narrative:

After being on a vector for traffic from ZME for approximately 10 mins, we were cleared direct to slt VOR approximately 350 mi away. We entered slt in the direct legs page and executed. After 1 min ATC asked if we were proceeding direct to slt and we checked and noticed we had failed to select LNAV and were still on our old heading. We learned to pay more attention.
