[Evolution] preventing ctrl-backspace from putting text into the clipboard

[Matt LeClair <matt nigdy net>]

I'm running Ubuntu Hardy with Evolution 2.22.3.1

I use ctrl-backspace to delete a word preceding my cursor all the time
when composing messages in gnome. However, I've noticed that the
behavior of this shortcut also cuts that text and puts it in the
clipboard. Applications such as openoffice or gedit, however, merely
delete the word and leave the clipboard untouched. I've used tools such
as glipper or parcellite to record clipboard history, but it's still
annoying to track back through it to find the string I want that I
literally cut using ctrl-x.

I'm not trying to tell you that ctrl-backspace shouldn't put text in the
clipboard - I have no idea what people like. But I would like to remove
this functionality for myself because I find it very annoying.

I searched the mailing list and found that others have suggested looking
at ~/.gnome2/accels/evolution
or /usr/share/evolution/2.22/ui/evolution-mail-message.xml

Does anyone know exactly how I would disable the cut functionality of
the ctrl-backspace shortcut in Evolution running under Ubuntu 8.04?

thank you very much,

Matt
