the idea of navindex was to allow the author to override
default document order and provide explicit navigation order
for special cases.
This said, your question is still a good one.

    Nolan,> <group> <textbox ref="..." navindex="1">
    Nolan,> <caption>Input 1: </caption> </textbox> <textbox
    Nolan,> ref="..." navindex="3"> <caption>Input 2:

    Nolan,> 	<group> <textbox ref="..." navindex="4">
    Nolan,> <caption>Input 3: </caption> </textbox> <textbox
    Nolan,> ref="..." navindex="2"> <caption>Input 4:
    Nolan,> </caption> </textbox> <group> <group>

    Nolan,> <group> <textbox ref="..." navindex="1">
    Nolan,> <caption>Input 1: </caption> </textbox> <textbox
    Nolan,> ref="..." navindex="4"> <caption>Input 2:
