Never having used a 3270, I'm probably way off the wall, but just in
case noone more knowledgeable answers:
        1) Forms are filled out using lynx's own line editor.  Your
           default editor is not called for filling out forms.  It's
           important to read the on-line help to learn about the
           key strokes for the line editor.  If 3270s can do:
                       Lynx Line Editor Default Key Binding (p2 of 2)
           [...]
           ERASE  Erase the line       -  Ctrl-U, Ctrl-X
           [...]
           DELP   Delete prev    char  -  Ctrl-H, DELETE, Remove
           DELC   Delete current char  -  Ctrl-D,
           for example, your users should be able to edit
           individual form boxes.
        2) Moving around on the form can be a pain.  I need
           tutoring in this area myself.  Moving down the form
           is easy; just press [TAB].  Moving up one input box
           at a time is not possible AFAIK, but on my terminal
           at least, you can use "Page Up" or "Home" to jump to
           above what you need to edit, and then move down again
           with [TAB].  The worst case is that you'll have to
           start always at the top of the form and [TAB] down.
        3) Press "x" on the Submit button, as opposed to [CR]
           to prevent cacheing.

Hope it's not wrong and helps someone.
