flight path mapping

[villageidiot]

For the lack knowing i call it mapping, My flight path is being shonw as a pink line, ive hit a hot key with out knopwing, what is this feature call and what key?

This would be the "O" key. Hit it a few times to show flight path, flight path and height, flight path and height in black, and ILS visualization. (If ILS is tuned proper)
