Shouldn't the MCE provide you with such a utility? Provided you send PF3 the correct key it will work and it doesn't care whether that's from your keyboard or any VR program, the end result is the same.
Yes, I agree and I have asked there as well.
It appears neither developer wishes to offer this tool for their customers...
However, someone here suggested Wordpad. Last night I used Notepad +++. As long as I place my cursor in that program (it has the focus), and then use MCE, I can see the key presses MCE passes.
When contacting Tower, I can confirm it does send first a 0, then a 1.
Using Notepad is OK, but using it prevents the key presses from getting to PF3. So, I have to place my cursor in Prepar3D and say the commands a second time. Not perfect, but at least I can see the key presses passed.
It just would be nice, if PF3 could have a debug mode, where the keys it
receives are displayed along with the verbiage displayed.
Anyway, thanks for your consideration.
