I have looked at the key card and posts but have found nothing yet.

I understand ,and use, F6 to get to the gun site view but you need to go through about 3 other views to get there.

Is there toggle or button that goes directly to gun site "on" and gun site "off"

And yes I have TrackIR and lean over to the site, not convinced its helping my accuracy, but would like a 1-button solution if possible.
