How do I get Ctrl-Backspace to delete a word in vim within gnome-terminal?

Question

I\'d like Ctrl-Backspace to delete the current word in vim insert mode. From within xterm I can pull this off via

:inoremap  

Answer 1

gnome-terminal's libvte would need to be patched.

libvte already has several options to map backspace, none of which distinguish Ctrl-backspace. It needs an option that does, maybe one that follows the behaviour of the linux console (^? for backspace, ^H for Ctrl-backspace). See this gnome bug.

2015 update: this was fixed in 23c7cd0f99d504cbab06d4c27254d4f3e2807ba8.

libvte 0.41.90, 0.40.3 and newer have the fix.
