......now you HAVE confused me, LOL, but that's not difficult to do at the best of times.
Actually it's dawned on me what I think you're driving at.
You hit F5 to go to the nav map but the toolbar keys don't change. You have to click on the appropriate tab in the toolbar to bring up the nav tools like the setting course tab or the return to course tab. Are we on the same page now, LOL?
If that's what you mean, it's definitely a valid question but to be honest it's never struck me before. I'm not sure there's a mod out there for that, but your idea makes sense. It's only natural that if you go to the map then your toolbar should automatically have the map tools displayed so to speak.
I don't really have this problem as I use SHIV Speech and I just say "map" into my mike and I'm there then I say "resume course" and I get an "aye sir, returning to course" etc.
