Windows 7 - Word 2007 - Links within a document? Hide/Show sections of a document?

I have two questions regarding documents created in Word 2007...

1) Can links be created within a Word document? For example, can I click on and item my table of contents and have the document jump to that particular section of the document?

2) Also, is there a way to make sections of the document hidden until the user clicks a specific word or graphic in the document?

I'd like to specify a particular instruction and include a "Show example" link that would make a detailed example appear for those who needed the extra help.

Thanks everyone!

If you created table of contents through References - Table of Contents, you can hold Ctrl and click on the item in that table, word will take you there. This feature is standard.

Also, to navigate inside document you can use bookmark option.
Insert bookmarks. Word 2010 Bookmarks
Then insert Hyperlink - in the window select second tab "Place in This Document" and choose your bookmark.

As for hiding parts of document, I do not think that is possible.
You can create that in HTML document with javascript, but not in Word document.

Great information Neutron16. Rep + to you.

I totally agree!
