What is it?
BUTTON is a TYPE attribute value to the INPUT element for FORMs. It places a button on an HTML form and uses scripting code to make the button perform an action you define (this is aside from the information that it sends in the Name/Value pair upon form submittal.) Note that this INPUT type does not actually initiate a form submission.

Tabindex

Required? No
Description:
"Tabbing" is a method of giving access/focus to an active HTML element using a standard keyboard sequence. All the active elements in a document can be cycled through using this sequence (ex: Windows TAB key.) The order of the active elements in this cycle is usually the order they occur in the document, but the TABINDEX attribute allows a different order to be established. The use of this attribute should create the following tabbing order cycle if the browser supports the attribute:
  1. Active elements using the TABINDEX attribute with positive integers are navigated first. Low values are navigated first.
  2. Active elements not specifying any TABINDEX attribute
Those elements carrying a DISABLED attribute or using negative TABINDEX values do not participate in the tabbing cycle.
Values: Positive or negative integers.
