Keyboard controls for MultiZilla & tabs

Hi there,

I hope this doesn't seem too whiny, I really like what MultiZilla does.  I
just have one problem that is driving me nuts and I think MultiZilla is
responsible.

I installed MultiZilla yesterday and since then I've noticed that text
editing in the browser (e.g. writing weblog posts) has become unbearably
irritating.

The reason is that Ctrl+Left-Arrow and Ctrl+Right-Arrow seem to have been
rebound from "word left" and "word right" to "previous tab" and "next tab."
You can imagine how irritating it is to be editing text and suddenly find
yourself 5 tabs away.  And because the old bindings are hardwired in my
brain I do it over, and over, and over...

I haven't figured out how to uninstall MultiZilla to confirm it as the cause
but I'm sure I'd have noticed it before now (I write several times each
day).  Also I've poured over the config options looking for some way to
change this and come up blank so far.

Can anyone help me?

Regards,

Matt
