Hi its me again with my favorite subject ;)
It looks like the keybindings additions to
/usr/X11R6/lib/X11/app-defaults/XTerm where left out with the 4.0 build,
please apply the attached patch, which adds back the keybindings and the
large scrollback buffer.
(In case you forgot, this fixes: backspace,del,home,end shift F1-F10)
Created attachment 418 [details]
patch XTerm app-defaults which fixes the keybindings
Fixed in XFree-4.0-0.28 from the beta2/snapshot dir on gribble.
