Narrative:

On climbout on the all-nighter to the east coast; we were given a clearance direct to pevee. As the pilot flying I brought pevee to the top of the legs page and somehow dumped the box. I tried typing in pevee to proceed direct but must have miss-spelled the waypoint. ATC called and asked if we were proceeding direct to pevee; we responded that we were working on it. ATC gave us a vector to pevee. We were able to load pevee; proceed direct; and re-load the entire route. I am not sure how I dumped the box; but I should have been slower with the box work; insured the pilot flying verified the proposed change and then executed. I also should have asked for a vector earlier when I dumped the box; instead of trying to type in the waypoint at night.

Title: A B767-300 flight crew suffered a momentary track deviation when their attempts to program a 'direct to a fix clearance' on their FMC; their active route was lost. ATC provided a vector while they reprogrammed the route.
