Hyperlink (Ctrl+K)
You can add hyperlinks to your document that give your readers instant access to information in another part of the same document. The hyperlink can be text or graphics. By using hyperlinks, you can provide information to your readers without repeating the same information on different pages.
 
The fastest way to create a basic hyperlink in an Office document is to press ENTER or the SPACEBAR after you type the address of an existing webpage, such as https://www.comteachers.com. Office automatically converts the address into a link.
 
In addition to webpages, you can create links to existing or new files on your computer, to email addresses, and to specific locations in a document. You can also edit the address, display text, and font style or color of a hyperlink.

 
To add links that jump from one part of a document to another part of the same document, mark the destination and then add a link to it.

Bookmark
Bookmarks allow you to assign names to text or to positions in your document. In this way you locate them easily, just like when you put a physical bookmark in a book to save your place. Once a bookmark is defined, you can use the Go To option from the Edit menu to move the insertion point to the bookmark location.
 
In Word, bookmarks are saved with the document file. Thus, you can assign bookmarks in different files that use the same name. Each file can have up to approximately 450 bookmarks defined. Names for bookmarks must follow these rules:

1. Names must begin with a letter of the alphabet
2. Names can contain only letters, numbers, and the underscore
3. Names cannot contain spaces or special marks

 
How to create a bookmark to selected text?
Select the text/location => Select Insert Menu => Click Bookmark =>Type a name for the bookmark =>Click Add button => Click OK. (To Run = Select your bookmark name in the dialog box and then Click GoTo => Click Close button).

Cross-Reference
When you are needed writing a long document, you may want to include references from one part to another. To avoid having to update pagination, headings or figure numbers, you can use Word’s cross-reference feature. Since Word inserts cross-references as hyperlinks, you can also use them to jump to the targeted location.
 
How to insert a bookmark by using Cross-reference?
Keep the Cursor wherever you want => Select Insert Menu => Click Cross-Reference Tool => Select a Reference type and Select Insert as Hyperlink check box and then Select a reference area in the Insert Reference to drop-down box => Pick a reference from your bookmarks => Click Insert button => Click Close Button.
