Well, the least confusing way would be to simply open the web browser, find a web page and use the menu commands at the top of the browser window to save a web page. Depending on which user you are logged in as, it should save to the home directory of that user, I think. Then you can open up a terminal window and enter "ls" at the command line. It should list the file you saved (probably .html file).
If you know how use the menu to open up a text editor, you could type something then save it . You should then see that file also when you are in your home directory and enter "ls".
