I've never seen a specific Chapter marker. It may be because commonly intra-chapter references are mainly to clarify the text inside a single chapter only, and each chapter may be supposed to stand on its own.
Techniques range from highly abbreviated to highly wordy, e.g.
See "Basic Introduction to Writing Long Texts" (...
Text Variables can be used.
Type > Text Variables > Define.
Then name it, I used Issue Number to go with your question and whatever text you want.
Then just for example I created two text boxes and did Type > Variable > Insert > Issue Number
Now when I want to update I just edit that variable
Didn't screenshot but hit edit, changed it to Issue 02 and ...
It's certainly possible, and I'm not able to find a problem with it in any of the current versions (CS6, CC, CC 2014) of InDesign. There were some issues with cross-references that spanned documents using the Book feature, but I believe they were fixed somewhere between CS4 and CS5.
Do make sure that your text anchors don't overlap (each should be a ...
If working with a .INDB file (Indesign book), with separate docs as chapters:
Primary section: set as numbered list - level 1. Create a new list, uncheck "Continue Numbers From Previous Document In Book" in the options, then name and save the list. (No need to set your "Drop cap" paragraph as a list)
Secondary section: set as numbered list - level 2. ...
Definitely after, just like a regular asterisk when placed in the main body of text. Then, before the referenced text when used in the footnote.
It is actually just another different looking asterisk, for when you need to highlight multiple references, so the same logic applies.
Set cross reference like this: <paraText /> <chapNum />
Edit: Ok after re-reading your question, I understand you'll be facing a problem: your variable is in the middle of your paragraph text (paraText). So the result would be "Chapter: Combat 6". Not good ^^
So I suggest this: Set your paragraph style as a numbered list. In the "Number" ...
In order to set up a cross-reference, InDesign has to ensure that it has the target page correctly identified. To do that, it has to know exactly what the page count of the book is. If the intervening chapter files are closed, InDesign can't be sure their page counts haven't changed, so it has to open them in sequence, check their page counts and update them ...
I don't have the time to explain in detail, but here's how I would do.
Sorry: because of filesize limitation, I have to split the animation in 3. It's not going to be easy to follow, especially because of the gif loop... But hopefully, you'll get the idea.
The good thing is that the trick also allows you to add aside annotations to your footnotes references. ...
Sadly, the simple answer is no. There is no option to simply pause syncing.
So really your only two options:
Keep all of your referenced files open while you're working.
Keep your referenced files on an external drive that can easily be un-mounted. then when you're ready to update the cross references just mount the drive and they should update ...
