LabVIEW
Subscript or Superscript in String Indicator
Aeh, i am really confused about your question.
If you place a string control, the "label" is already shown and marked for change (simply start writing). Since the label is the programmatic name of the control (which should be unique on the panel), you should keep that short and understandable. The label is shown on the block diagram at the terminal for the control.
You can use the context menu to display the "caption". This is the descriptive name on the panel. Use this for longer names/localization purposes.
You can move label and caption to your liking, so a caption can also be a string below the control (visualwise).
As an alternative, you can use "free labels" (double click somewhere on the panel where no control/indicator/decoration is placed) to give descriptive hints for using your application. Those can be moved around as well. You would want to group them with controls if needed.
hope this helps,
Norbert
[EDIT] If you refer to text within a string control, you cannot use "sub" or "superscript". The options you can use are the following (screenshot of selection menu of property node "Text.Font"
