In today's tabbed browsing world, maybe you find yourself opening and closing tabs left and right. If you're into the keyboard shortcuts, that would be Ctrl-T and Ctrl-W respectively 
What if you accidentally close a tab? This happens to me most often when either I thought I was done with the website I was on, or I thought the tab I was on was a new tab with nothing to go 'back' to.
Fortunately, the good browsers out there offer a Ctrl-Shift-T keyboard command to open up the last tab you closed. I like to think of it as the "ctrl-z of browsers". This keyboard command is very handy because you can actually keep pressing Ctrl-Shift-T to open up all the tabs you previously closed. Each tab you re-open not only opens up with the page you were on when the tab was closed, but the browser history for that tab is also preserved. So once you re-open a closed tab, the entire 'Back' button browser history is there.
Ctrl-Shift-T works in Firefox and Chrome. It doesn't appear to work in Safari/Windows and doesn't work in IE7. That's what I meant by this keyboard shortcut working in 'good' browsers 
It does appear to work in IE8.
Since discovering this keyboard command it's something I use probably at least once a day. Sometimes many times a day!
