>Description:
Some software, notably dialog(1), can understand back-tab, which is typically bound to Shift-Tab.  syscons produces ^]]Z for Shift-Tab, like many VT100-like terminal (emulators). The plain xterm does not produce this sequence, but ^I for both Tab and Shift-Tab.

For compatibility with xterm-compatible terminal emulators, adding a kB attribute is desirable.
>How-To-Repeat:
On the console,
$ dialog --menu foo 20 60 12 a one b two c three
Hitting Shift-Tab exits from dialog.

>Fix:
Add :kB=\E[Z: to the xterm-basic entry:
