Something I have always wondered but never got around to asking. How does one put up 2 or 3 different workable tabs at once on the same computer screen?
Do you mean within a web browser? If so it probably depends which one you are using, but I think a standard function across them all is to hold down 'Control' and click on a link to open that link into a new tab.
I use multiple tabs all the time with my web browser. It's very convenient when you need to look at one page while you are working on another. Of course web browsers now have the tabs available at the top of the page which makes it much faster.
