Using vim through terminal in OS X, I don't seem to be able to bind meta-backspace to delete a word.
I'm using xterm-color, delete sends ctrl-h, and I have 'Use option as meta-key' checked. This works well for everything else.
^w does the same thing in vim, but my fingers are trained to use option-backspace (delete key on mac keyboards).
In vim through the terminal, if I type i then ^v then meta-backspace I get nothing. In MacVim, I get , which is correct. So it seems to be a terminal encoding problem. Any help is appreciated, I can't imagine I'm the first to try to do this, although there are enough issues with backspace in terminal that it makes googling difficult.
