Mr Moonlight,
First of all - THANKS!!! S&T hotkeys is working!!! I've programmed my mouse to use left and right clicks for F6 (insert pushpin at current location) and Insert (toggle GPS trail). Now, while driving I can simply click a mouse button to start and stop the GPS trail as needed, and to insert a pushpin at current location. As far as I can tell, the program works as intended, except for one thing that may or may not be related to S&T hotkeys.
While driving and the GPS trail is on, I can see the trail is correctly tracking where I'm at. I can verify the accuracy of the route by overlaying the saved .GPX file in Google Earth or ArcView - the route is very accurate, at least accurate enough for my purposes.
What's strange is when I use the F6 key to insert pushpin at current location, the pushpin is inserted, but the pushpin accuracy is pretty bad, especially compared to the GPS trail (I would think the accuracy of the GPS trail and the pushpin location would be identical?). Most of the time the pushpin is inserted 60'-140' off the GPS route line - in one instance it was inserted 430' off the route line. Please see
this image file that clearly shows this. This image is from ArcView, but it looks the same in Google Earth, and the pushpin location is clearly off the route path in S&T as well, just not as obvious without the imagery in the background.
Please note that I realize pushpin accuracy while driving/moving is prone to errors for obvious reasons. so each time I inserted a pushpin the car was completely stopped, and it was still way off from what the GPS trail was currently tracking. Also, the "Provide Navigation" box was NOT checked, so routing was not being "snapped" to roads. As far as I know the GPS trail is what the GPS receiver was actually picking up and it's fine, I just need the pushpins to better fall in line with the GPS trail.
