I am so used to using ⌘D to "delete-next-word" in emacs and xterm, that I automatically hit it in Terminal all the time, which rather annoyingly (to me, at least) causes the pane to split instead. I've tried to google solutions, but all I get are hits telling me what a neat feature this is.
I could just use XTerm under X11, but Terminal plays more nicely with some of my favorite Mac utilities (notably Divvy). I've tried iTerm2, but at best I can get it to ignore ⌘D, not actually erase the word.
Any ideas?
