[AARPRazorbacks]

To start the engine I would like to use one key but can not find what key that is. Below is what thy say--------- but not were or what key to use to reset this.
Anyone know?

Thanks,

Another important constraint enabled by this option is what was in previous
titles called a (Separate Engine Start) option. This option is independent of
the Complex Engine Management settings. Pilots in real multi-engine aircraft
had to start up each engine separately. With Anthropomorphic Control
option disabled you will be able to start up all aircraft engines with a single
key. Otherwise you will need to individually select and start up each engine
in turn.
