No that doesn't work for me F3 simply switches me between Cockpit on and Cockpit Off.
Here is the scenario.
I am running in virtual pit with Track Ir enabled.
I close the bandit for guns and switch to Iron gun sight view (F6) ... Looking over the sights. (track Ir now not panning).
The bandit moves out of the field of view. I now want to quickly (single key press) revert back to my previous view i.e. Virtual cockpit.
At present the only way I can get back to Virtual cockpit view is by multiple F6 presses. Each press stepping to a new view like Fuel gauges etc. I keep pressing F6 until I get back to virtual cockpit view. Whats more the number of F6 presses required varies for each aircraft type.
So In summary all I want to be able to do is snap between Iron sight view and virtual cockpit as required with a single keypress.
