A Stripped Down Manual Reordering of Lines for a Field

[Michael Mandaville]

I have been studying Jan Schenkel's excellent stack on Manual Reordering.
I'm taking it apart to learn.  Also another stack called "Get in Line".

But I wanted to know if there's a stripped down version of Manual Reordering
for a field.  The user would select certain controls, buttons, A category
and input text into a field.  Then this A [tab] Category [tab] User Input
would go into a field.

I'm trying to find some simple code for Manual Reordering by the User.

Thanks for your help.  I'll keep studying the other material, but just need
a jumpstart.
