Comment 8 for bug 359180

First attempt:

tabindex 1 - cycle through input and textarea
tabindex 2 - Save and continue button

accesskey s - Save and continue
accesskey f - Focus the search field

accesskey r - Go to first
accesskey n - Go to next
accesskey p - Go to previous
accesskey l - Go to last

Here is an excelent resource about tabindex implementation in browsers
