Create Hyperlink sets up a hyperlink to a specified cell, notebook, or URL.
1. Select the words you want to make into a hyperlink.
2. Choose Create Hyperlink.
3. Specify a destination for the link. The destination can be a notebook or cells in a notebook.
4. Click OK.
The selected text is formatted as a hyperlink button (typically underlined). When you click the hyperlink, Mathematica will jump to the linked cell or notebook.
Cells are targeted by use of cell tags. If your destination cells do not already have cell tags, you must add them first by using the Add/Remove Cell Tags command in the Find menu.
On some versions of Mathematica you can also link to a URL. Enter the URL in the text field at the top of the dialog box. Such a link will automatically open your web browser and connect to the designated web address. URL prefixes include "http://", "mailto:", "news:", and "ftp:".
When you click the hyperlink button, it jumps to the referenced cell. If you want to jump to this cell from a different notebook, check "Include file name in link destination".
A hyperlink is a ButtonBox object with the options ButtonStyle"Hyperlink" and ButtonData"destination".
To edit the name of a hyperlink button, click beside the button and use the arrow keys to move the insertion point into the button's text.
