SE61 - Docu Maintenance? Xplain

Dear all,

I have come across the T Code SE61. I have created a (F1 help) document for one of the data elements' that I had created. I never knew what are & how to use the other things in this (Business Add-Ins: Implementations, Class attribute, Class event, Class, Data element, Data element supplement,..........., Test information, ..........ABAP). So can you explain me all the concerns of this T Code : SE61. Also 2 Push buttons are there in this screen at the top "<b>WORKLIST</b>" and "<b>AUTHORIZATIONS</b>". Kindly let me know if why are these Push buttons used.

Would highly appreciate & be thankful to you.

Thanks in advance.

Regards.
