I'm using Access to loop through records and write to a Word document using CreateObject("Word.Application"). That is all working out well and now I'm attempting to apply formatting. I decided to have it utilize a template when I'm adding the document.

 set doc = .Documents.Add("MyTestTemplate.dotx")
This is doing exactly what I want so I have my margins, font, font size, etc. all set automatically.

The word files that I'm creating need to contain hidden text being used for tagging that will be needed in a system that these files are being uploaded into. The hidden text is on the same line as text that needs to be visible and I'm struggling with how to do that all in one line as I'm writing to the Word document.

For instance, in my example below "{HSTLA}", "{HSTRA}", "{HSTLB}" and "{HSTRB}" should not be visible when I open the Word document. 
{HSTLA}Sample text line 1 here that is visible in the file{HSTRA}
{HSTLB}Sample text line 2 here that is visible in the file{HSTRB}
The examples that I'm finding are applying the hidden text to a full section instead of pieces of one line and I'm lost how to apply it to my situation. Any help would be greatly appreciated!
