Please add SHIFT+TAB (backtab) to your list. Some (granted poorly-designed) websites sometimes require a change further down and then have to go back up to do something For instance, in sending a gmail email message in one snippet, I need to click on Bcc: first to get the fields right, and then I have to manually go up to the To: line for things to work properly. It'd be great if it could handle the back-tab up to the To: line for me.
