CHECKBOX is a TYPE attribute value to the INPUT element for FORMs. It
indicates a form field used for a boolean choice, or for attributes that
can take multiple values at the same time. The default state for a
checkbox is OFF.
Description:
This is a method of giving access/focus to an active HTML element using
a keyboard character. This is a common GUI paradigm also known
as a "keyboard shortcut" or "keyboard accelerator"
A single character is used as the value of this attribute. In addition,
a platform-dependent key is usually used in combination with the
ACCESSKEY character to access the functionality of the active field.

character set.

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:
Active elements using the TABINDEX attribute with positive integers are
navigated first. Low values are navigated first.
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.
