How to make boxes independent from those cell-formatting options?

Question

In a cell whose LanguageCategory option is "Input", boxes will be syntax-highlighted. Is there any way to diasble such cell-formatting behaviors for inner boxes?

Additional Requirement: No inline cells should be used. That makes the Tab key unable to be used for jumps between placeholders. (There're more side effects not mentioned for inline cells.)

Example

(* highlighted *)
CellPrint@Cell[BoxData@RowBox@{"boxA", "boxB"}, "Input"]

(* disable highlighting for one box with inline cells *)
CellPrint@Cell[BoxData@RowBox@{"boxA", Cell[BoxData@"boxB", LanguageCategory -> None]}, "Input"]

(* jumps between placeholders fails, so I don't want to use inline cells *)
CellPrint@Cell[BoxData@RowBox@{"boxA\[Placeholder]", Cell[BoxData@"boxB\[Placeholder]", LanguageCategory -> None]}, "Input"]

Other cell options to be screened

• ShowStringCharacters
• ... (Most of the options in StyleData["Input"] in Core.nb)

Answer 1

It seems that you can use the StyleBox:

StyleBox["boxB", LanguageCategory -> None]

(*highlighted*)CellPrint@
 Cell[BoxData @ RowBox @ {"boxA", StyleBox["boxB", LanguageCategory -> None]},   "Input"]

(*jumps between placeholders works*)
CellPrint @  Cell[ BoxData @ RowBox @ {
  "boxA\[Placeholder]", 
  StyleBox["boxB\[Placeholder]", LanguageCategory -> None]
},"Input"]
