Hi, I just spent a while exploring this and I couldn't force the page to place the cursor into a certain field or section. I'd be interested to hear if any has any advice on this, I couldn't find any other help. If you do figure it out, please let us know.
Oh man Jason is right - anchor tags for whatever reason don't work on the edit page! Sometimes it works, strangely, but it's not consistent. I played around with different solutions too and couldn't get something solid in. I suspect you may need a more creative mind or Javascript!
Detail page sections should have ids similar to this: head_1_ep
Hardcode the #head_1_ep into the URL and it should jump there!
