What is tooltip delay?

When should you not use tooltips?

1. Don't use tooltips for information that is vital to task completion. Users shouldn't need to find a tooltip in order to complete their task. Tooltips are best when they provide additional explanation for a form field unfamiliar to some users or reasoning for what may seem like an unusual request.
