Navigation sequence
This term is defined by more than one standard, and the wording differs. Each definition below is the one that applies to that standard’s criteria.
Definition in RAWeb 1.1
Order in which the focus moves (to the next element or to the previous element). The natural order is the one implemented in the source code. When it is modified using the tabindex attribute or using a JavaScript command, it is the modified order that is referred to.
Warning: when an element initiates a change in the page (change of context, management of hidden zones, addition of content, management of form fields, etc.), the element initiating the change must be activated in order to test the consistency of the navigation sequence.

Definition in RAAM 1.1
The order in which the keyboard focus moves (to the next element or to the previous element).
Warning: when an element initiates a change in the screen (change of context, management of hidden zones, addition of content, management of form fields, etc.) it is necessary to activate the element initiating the change in order to test the consistency of the navigation sequence.
Criteria in RAAM 1.1
Definition in RAPDF 1.1
The order in which content is scrolled through using the tab key. This sequence can become inconsistent in certain situations, for example when clickable elements are inserted into complex shapes or text areas and these are not presented in a consistent order. Similarly, in a PDF form, the navigation sequence of input fields and buttons can become inconsistent when they are incorrectly positioned.
