Up to now I have used the following procedure – still wondering if there can be found an easier way:
Position insertion-line on link-place within the (text-) cell of the notebook.
Type ctrl-9 to produce inline cell.
Enter Hyperlink-expression into inline-cell:
Hyperlink["text to be shown",{"HyperlinkTarget.nb","targettag"}]
(be sure the inline cell content is selected) then menu-draw "Evaluation>Evaluate in place" or Ctrl+Shift+Return
The (text-)cell with the hyperlink text "text to be shown" should be working. (Mathematica 14.2)
