Great ! I was able to discover this after a bit of experimenting while I waited for your response. I think your manual needs to add how to turn off online monitoring to the on-line monitoring section where it shows very well how to turn it on.
I normally start online monitoring by using the controller/online monitoring pull down. Ctrl-M is nice to turn it on - possibly the Ctrl-M function could be a toggle so it can both start and stop online monitoring

During debug the very nice online monitoring is used extensively so an easy and similar way to turn it on and off could be very helpful.
Thanks to all.
