Well, I'm using Firefox and at the very top of the page there is a little line of tools in a bar. One of them says "Bookmarks". Click on that, a drop down box appears and one of the choices is "Bookmark this page". Click on that and another box will appear with browsing controls so you can put it where you want it. Click on the location you want then click "Done" and it's bookmarked.
That's with Firefox. I 'think' IE is similar. I have no idea about Macs or any other systems.
