This stack uses the ToolKit™ XCMD TKhyperText which allow you to watch the cursor movement over the text in a locked field.  You simply write an "on mouseWithin" handler in the field being watched with a call to TKhyperText.  The default style is bold and underlined.  TKhyperText watches to see when the cursor is over a particular style.  You can specify a different style by passing a single parameter with the call to TKhyperText.  For example, TKhyperText "UBC" specifies Underlined, Bold, and Condensed style.

If the cursor is detected over the spedified style then all the words that are within that style are placed in the global gTKHyperText.
