I do like the idea of ALT+LEFT/RIGHT, as CTRL+TAB and CTRL+SHIFT+TAB can be a bit cumbersom, and people may be used to using ALT+LEFT/RIGHT in Internet Explorer (and other browsers).
Personally, CTRL+LEFT/RIGHT would be easier, as the CTRL key is closer to the arrows on most keyboards. I could see myself using that instead of the mouse for a change.
