want to skip 30 seconds each step change.
INCREMENT 7u

Increment a slider by one step value. The step size is defined by the
owner of the semantic node that executes this action. For example, a

enum class LabelOrigin : uint32_t
Name Value Comments
UNITIALIZED 1u

The node does not have a label yet.
ATTRIBUTE 2u

An attribute of this element in the runtime UI explicitly sets its
label. For example, an element with aria-label.
ATTRIBUTE_EMPTY 3u

An attribute of this element in the runtime UI explicitly sets its
label to be empty.
CAPTION 4u

This label serves as the caption for a table-like element. Because some
assistive technology have special modes to deal with tables, a runtime
should mark its label with this type of origin so that users know what
the table is about when they navigate in the table mode. For example,
a
<
caption
>
html tag sets the label.
CONTENTS 5u

This node receives its label from the contents present in the
application. For example, text from a web page becomes the label of
this node.
PLACEHOLDER 6u
