The Link command creates a hyperlink data structure to be used in conjunction with the Text command.

The url is a string of the form "http://www.maplesoft.com", and is the destination target page that should be opened when the link is clicked.

The expression is the text or math expression to click on.  

Note: When viewing a canvas containing a hyperlink in Maple with the ShowCanvas command, the text containing the link will be static; and won't be modified by any script commands.  Also, when the link expression is not a string, in Maple it will be prefixed with clickable text.  These limitations are not present when using the same canvas in Maple Learn.

The Link command should be used as a % parameter's argument in a call to the Text command.  Links are always embedded into a block of text or math as MathML attributes, and are not stand-alone canvas elements.
