A couple of weeks ago I was at a customer site providing some training when we were talking about getting field information (I usually do the ctrl+shift right click -> Debug -> Show Response XML)
Iit was pointed out to me that in Smart Office there is a Monitor menu item. So if you go in to a non- A or B panel (eg. MMS001/E) and right click on a field and select Monitor -> Show All
The fields will change colour and now we can hover over any of our non-calculated fields and…
…we can see the field name and the table that the data came from.
Pretty kewl isn’t it!
Thanks Eric for pointing this out to me.

Yes it seems like there were many people using this for other stuff than watches. In 10.2 there is no support for watches so we removed the monitor menu.
It didn’t take long before a partner emailed me about the missing watch menu. So we added the functionality back in fix 1 or fix 2 but then the menu says “Advanced” and Show Field Information. You can also select copy field information to copy the information to the clipboard.
