IQ-tips: Computer Timesaver Tips

Some of you may know some of these tips, but if you're like a lot of people out there, you may not know them all. Today, I present 4 tips that will help speed your life along while working at the computer. If you know some other PC timesaver tips, by all means, don't hesitate to drop them down in the comments and let us all in on them.
1. No need to type www
That's right! When typing a URL into a Web browser, there's no need to waste time typing the www part. Don't believe me? Go ahead and type mentafloss.com into the browser and watch what happens. [ed. note: As some readers have correctly pointed out, this is only mostly true. Some URLs still require the full www. But that shouldn't stop you from trying it first without!]
2. Alt + Tab (Apple key + Tab)
3. Tab through forms
Let's say you're in the middle of filling out a profile on our site. You're confronted with dozens of empty fields that need filling in (First Name, Last Name, Address, blah blah blah, you've done it a million times in your life already). What a pain in the neck it is to use the mouse to move through the boxes. You don't have to, though! Just hit the TAB key and shazam! you're in the next box. Make a mistake? Hold down the SHIFT key and then TAB back a box. HUGE time saver.
4. No need to go to Google.com to perform Google searches
Your turn! Hit us back with some shortcuts of your own.
