When working Chrome, remember that pressing Control-Shift-T will reopen the last tab you closed....I posted this a while back, but it is worth a quick reminder! I use this trick all the time and it saves me more often than I would like to admit.

Oh, and here's a bonus. Control, plus the letter F will open a search window on a webpage or document, usually on the top right corner. If you type in a keyword in that box, it will quickly find what you are looking for on a page and tell you how many times it appears on that page. Using the arrows or next button on the that search window will move from one instance to the next of whatever you searched for...enjoy!
