Camino Question

So I finally got sick and tired of Firefox’s instability on Mac OSX and installed Camino. One thing that’s bugging me is the “find-as-you-type” feature. How do you get it to search for search terms with spaces? As soon as I type a space it stops searching! I tried googling… but to no avail.

Edit: Also, when you’re using System Preferences to set custom keyboard shortcuts, how the hell do you use “tab” in one of your shortcuts? I want to use ctrl+tab as a shortcut, but it won’t let me!
