When running emacs insde of screen, screen helpfully turns the backspace/delete key into "^[[3~", which gets turned into a forward-delete. Unfortunately, just bashingdeletechar
intobackward-delete-char-untabify
causes backspace in incremental search to cancel the search, which is annoying.One option is to set the TERM env var to rxvt:
% setenv TERM rxvtBefore cranking up screen.
