How to remap keyboard

Hello,

  I have checked the archives and found several references to this, but
I don't find the files listed as needing modifying.

  I have installed tn5250-0.16.0pre2-1 (from an RPM a coworker
downloaded) onto a fresh install of RH8.0

  I found the xt5250 script to change the font size.  But I am having
troubles with the changing keyboard functions, our users expect the
standard 5250 keyboard layout, Enter key = field exit, <Right> CTRL key
= Enter, etc.  I found references to changing these in the .Xdefaults
file, of which I can't find such a file anywhere.  Also referred to
.Xresources file, which does not exist in the users directory, I do find
it in ROOTs directory though.

  Do I need to update some files somewhere? Get a new tn5250 RPM?

Thank you,
Mike
