The calculator widget that comes with the OS!
This is a great tip submitted by Elizabeth Tremblay: The calculator widget that comes with the OS! Sometimes, it is such the simplest tips that are the most useful. I really wondered when I saw this tip why I never actually figured it out before this. When you are using the calculator widget that comes with the OS, it is so much faster to use the numeric keypad (even for the +, -, * or / symbols) than to use the mouse. What really bothered me is that I always had to go back to the mouse to clear it and start again. Well it turns out that no, instead of pressing the "c" button on the calculator with the mouse, you can simply hit "c" on the keyboard. It will clear up what is currently in there and you are ready to start calculating again! Thanks for the great tip Elizabeth!
