Google Chrome user? Try this handy tip. Not sure if this will work in the other browsers; but, you may want to give it a try. To me this tip is pretty handy, especially if you are researching something and you need to open another browser tab in the background. I found two ways this will work:
1 – Hover your mouse on a link on a web page and CLICK your MIDDLE MOUSE BUTTON and the link will open in a new tab (in the background). For some reason, the type of mouse that I have, this did not work; however, other mice I have used, this does work.
2 – A workaround, if your middle mouse button does not work (like in my case), is to hover your mouse on a link, is to push down the CTRL key on the keyboard and LEFT MOUSE CLICK the link. Again, this will open the link in a new tab (in the backgound).
