Most people happily go about their web page surfing, left clicking on links as they go, just accepting that the link will either open in a new window, a new tab, or replace the page they are currently on, but never knowing what it will do until it’s clicked. If the last one occurs, and you weren’t ready to leave that page, you’re stuck hitting the back button to return to the page you were on but then you lose the page you linked to. A vicious cycle occurs.
Did you know that if you right click on the link, instead of left clicking, you can choose to open it in a new tab or new window yourself? That comes in real handy if you are doing research and want to keep different pages/tabs open.
Additionally, depending on which browser you are using, you will find other options under the right click menu. For example, you can copy the link, bookmark it, save it, WOT it, email it, etc.
