TKHyperText allows you to define a style run within text, such as bold and underlined. When the cursor is over the text it will turn into a magnifying glass when it encounters the specified style. TKHyperText places all text within that style run into a global which you can examine on a mouseDown/Up script.
HyperText is particularly useful in informational stacks as an optional and intuitive way to direct users to more specific information.
