I've got a form and I'm trying to make it so that if a person pressed the "." (period) key on their keyboard while typing in a text field the cursor moves on to a different field. Any ideas on how to achieve this?

use a onkeyup | onkeydown | onkeypress event and

if (event.keyCode == 190 || event.keyCode == 46) {
// do the focus setting routine here
}

190 is the full stop (period) key and 46 is the numeric pad del key
