Often it's the little things in life that make me happy. Control-F makes me happy. Or more accurately, Control-F when I was using a PC. Now that I'm using a Mac my heart belongs to Command-F. They both do the same thing. F is for find. And they let you find text on a web page. That's it. Doesn't sound like much, but oh my, the time it saves you.
I'm sure you've had the experience of googling a search term, then clicking on a resulting link and being totally baffled about why google sent you to that page. If you wind up on a page that has a lot of text and goes on forever, it can be really tedious to search through it looking for what you're interested in.
So, just hold down the Control key (the Command key on the Mac) and hit the letter F at the same time. Then look around. A small pop-up window will appear somewhere on your browser. Might be at the top, might be at the bottom. Just enter the term you're looking for and it will get highlighted for you. Try it right now, on this page.
Happy?
