and an other newbie question: how can one toggles through the waypoints i.e. to have them at the center of the map display ? (for example to check the flightplan on a long flight)ThanksKarim

Select PLAN mode on the EFIS control panel - you then get a STEP > prompt on the FMC legs page at LSK 6R that moves through it. The NEXT and PREV PAGE buttons will also step through it in larger increments.
