I am using Widgets on Pages to place some live content on my posts. I can see the fields boxes for the widgets on my post admin page and they work as expected, but what I would like to be able to do is to use custom fields so that I can change the values that way. Is there a way to see what the custom fields used by a widget are?
Also, I found that I was not able to name a custom field with _ as the first letter. Is that typical?
