Wow! I just found this while searching for something else...
I can't find the thread about this, but I thought it should get posted...
I'm a bit surprised no one pointed this out?!?
There IS a shortcut to toggle the PRV snap... the shortcut is:
Shift-Alt-N
That will save some time though it's a difficult single hand toggle...
Now to find a way to keep grid follows snap from reverting to Global snap values when PRV snap is toggled!
Please excuse me for posting this a second time. I couldn't find the thread for this topic and I posted it in a thread about a different topic, so I thought it might interest some people who might not see it any other way...
