A forum post makes the point, it's useful to switch auto coordination, say, when taxiing after flying with the prop active. Alt-c _A_uto _C_oordination looks to be available:
keyboard.xml : 997
<key n="99">
<name>alt-c</name>
<desc>Toggle Auto-Coordination</desc>
<repeatable type="bool">false</repeatable>
<mod-alt>
<binding>
<command>property-toggle</command>
<property>/controls/flight/auto-coordination</property>
</binding>
</mod-alt>
</key>
I'm always nervous of making any change in the default keyboard.xml, becuase different langauges and systems map the 'strange' keys (alt- and/or ctrl- pressed) in different ways.
One option is we simply try it and see who complains, but I might ask on the developer list, if anyone knows for sure a reason alt-c would work or not work?
Just a comment on the idea.
Perhaps Alt+NumKeypad5 (if available) would be a better choice? As the NumKeypad5 is used to center controls, it somehow looks more naturally connected to enabling auto-coordination.

Of course, keyboard preferences are highly subjective but I would point out, the numpad is absent on a great number of keyboards. For myself I already use the numpad plus and Ins to initiate combined roll with rudder, while numpad Enter holds the turn.
Auto-coordination toggle is now bound to <alt><2>.</alt>
