Hi,

Sorry for the late reply.
Well, as you suspected: KEY_BACKSPACE also does not work in normal ncurse
programs.

The data:
I use rxvt-unicode
TERM=rxvt

the infocmp output is appended below.
If my terminal is sending the wrong character, can I somehow tell cdk to
reeinterpret that character?

Thanks!
