Most WEB Browsers (i.e. Mosaic, Netscape, AOL, Compuserve, etc.) will display certain words in blue and sometimes underlined as well. In rare cases these anchored words will be some other color.
In any case, if the word is about something that interests you -- click on it. These words are anchors and will link you to more information or back to strategic branch points. Feel free to click and tour.
Use the Back button located on the tool bar of most WEB Browsers. If you don't see a button, you'll probably find a Back command in one of your drop-down menus. In either case, you will immediately return to the previous page.
The Back command is a handy way to back-track when you stray a little off course. Use it.
Setting a Bookmark is the fastest way to return to a specific WEB page from virtually anywhere on the Net. Setting a bookmark is easy. The trick is organizing your bookmarks in a way that makes sense to you.
Believe me, in no time you'll have set 100+ bookmarks. It gets real cumbersome to view each one when you want to review past points of interest. Refer to the help screen of your WEB Browser and search under "bookmarks" for instructions on setting bookmarks.
