GRT Avionics

Let's say I am in the sequence mode following a flight plan, and get clearance from atc to a point well down the line. How do I go direct to that point without leaving the sequence mode, so as to not lose my waypoint string following the new direct to point?

The older EFIS models (WS and HS) do not have this function, which is called "Go Direct" in the newer software on the HX, HXr, and SX. In the older software, you would have to switch to direct-to mode to fly to the waypoint, then switch back to the sequence mode and change the leg.
