Ya know, I was told that the MFD's were supposed to be pre-programmed for the Harrier but I didn't see that. Prior to programming them myself, if I pressed the bottom middle key on one of the MFD's, it did not result in the Menu key on the MFD in the sim being pressed. So I had to go in and redo them myself. The TM MFDs' buttons are numbered 1 - 20 starting at the upper left hand corner and go clockwise from there. All of the MFD's in the sim for both the Harrier and Hornet start their numbering at the lower left hand corner and go clockwise from there.
