Link to "virtual popup" that displays the contents of the "How To" Guide, which might include:
How to Export
How to Connect from Off-Campus
How to Order a book from Connect NY
How to Order a book from the Inter-Library Loan
Because the How To Guide is heavily cross-referenced to other areas (like the Search Results and the Reference Desk), it can also be invoked from other relevant locations in the site.
A "how to" module might simply be an ordered set of instructions, or it might be a more sophisticated, illustrated, animated tutorial.
