Xdefaults has the same format as the XTerm file installed in 
/usr/local/share/tn5250.  There is  documentation on Xdefaults in 
general available on the XFree website, but that probably isn't what 
you're looking for.  The part you're interested in is the Translations 
string (xt5250*VT100.Translations) which describes how keys relate to 
values passed to xterm.  The tn5250-HOWTO contains info on how to make 
the map.  From the HOWTO, in order to make enter on the 10-key pad be 
field exit put the following in your ~/.Xdefaults:

xt5250*VT100.Translations: #override\n\
        <Key>KP_Enter: string("\033X")

Also look in the appendix of the HOWTO for complete examples.

The HOWTO is located at:

If you have read it and it still doesn't make sense let me know.  I've 
tried to make it as simple as possible, but perhaps the keymap section 
isn't very clear, or perhaps it could use more illustrative examples.
