So far there are no assignments for any K events that use the panel option. For example the heading bug will not update to the current heading for older type mechanical gauges.
Basically non glass.
Need assignments for K events like:
AP_PANEL_HEADING_HOLD
AP_PANEL_ALTITUDE_HOLD
AP_PANEL_MACH_HOLD
AP_PANEL_SPEED_HOLD
AP_PANEL_VS_HOLD
There may be more.
