NEW UNDERSTANDING! I was confusing the current stop-point as a breakpoint symbol. It appears Cntrl-B Does toggle the breakpoint - but there is no visual evidence that it has been removed. I now see the breakpoint is a diamond-symbol when added - but doesn’t show again while running. It would be very helpful if there was like a red-dot for an active breakpoint - which would disappear when the breakpoint is removed. Also a clear-all might be nice.
In Processing 3.3 it appears that breakpoints be come a “permanent” part of a sketch. Days later when going back to a project and debugging new probs - I keep hitting previous breakpoints.
Is there any way to just clear them all and start fresh?
