Given the fact that this document was meant to document both the Quickshifter device and the Windows software application it communicates with (since the pair of them are delivered together as one product), the title over the links to the sub-pages did not quite make sense. It appears to assume that the title of the page "works" in the wording of that title:
"The contents of <page_title>"
and I can already tell this isn't always going to work.
It is gramatically incorrect. This is a title, and so should be capitalized according to the rules for titles in English: "The Contents of <page_title>" with a capital "C" on "Contents".
Because my <page_title> is the product name of the Windows software application, as opposed to the title of the document, it winds up being a mis-nomer. It "kind of" works if I rename the page title to be the title of the document instead by adding "User's Guide" at the end.
What I'm wishing for right now is the ability to have that character sequence as a "default" with the ability to edit it, say in the Page Properties Window on the left.
To my delight, I found a decent solution, if not perfect: in the Project Settings is a place where I can modify the prefix to the <page_title>, including having none at all. It is available in Project settings > Text strings.
I changed mine to: "Contents of" so the resulting title reads "Contents of <page_title>"
And then I renamed my help document to HM_GP_Shifter and added "User's Guide" to the end of the two immediate sub-topics.
