I'm assumimg by your reference to the XTerm file that you're doing this for xt5250. 1) Open a normal xterm and set your terminal type to xterm-5250. Type "export TERM=xterm-5250" for sh & bash style shells or "setenv TERM xterm-5250" for csh or tcsh style shells. 2) Go into vi, hit i for insert, then Ctrl-V to tell VI that you want to see the control characters of the next key you press. 3) Press your backtab key. The control characters should display on the the screen with escape being represented as ^[ 4) Change the XTerm file to match what vi showed. In my terminal, it shows ^]Z (which would be \033Z in XTerm) HTH...
