I've lost count of the number of times I've groaned after learning the simplest of technology-related time savers — say, auto-resizing columns in Windows. In this TED video, CBS' David Pogue covers ten similar shortcuts to speed up your daily computer and gadget interactions.
I think a majority of tech-savvy users will know about pressing Tab to shift between box on web forms (or any form, really), or typing letters into combo / drop-down boxes to quickly jump to certain options. But I had to suppress a facepalm when Pogue mentions using space bar to "scroll" down a page and Shift + spacebar to go back up. It's sure going to be hard giving up the mouse wheel / trackpad / down arrow.
I'm not so sure about the "skip to the beep" tip, which only covers US carriers, but hopefully there are equivalents for local providers — be sure to comment if you know any.
