I have been using computers for something like twenty years now. I regularly use most shortcuts I know and this, combined with a touch typing intensive course and ten years of piano lessons in the past, makes me fast. Very fast.
You may very well imagine my astonishment when - purely by mistake, as I was eating lunch at my desk and my index finger was greasy with Tesco Finest Sundried Tomato Dressing - I noticed that I could hit the right button on the mouse with my middle finger. It makes sense really, rather than switching buttons over and over again in some frantic digit aerobics. Perhaps if I left-clicked with my index, right-clicked with my ring finger, and scrolled the mouse wheel with my middle one, then I could be really fast. On the other hand, that would see me out of work sooner than planned, as I would be through with my job before the end of the contract. I suppose I'd better start pretending to be typing with two fingers and looking for the keys. Now, where was that fullstop key again? Oh, there it is.Update: multi-tasking with my right hand is opening up a whole new world of possibilities. I'm starting to get the hang of it, and earlier today my index left-clicked while the middle finger scrolled the wheel up to the end of the selection. As soon as the index released the button, my ring finger right-clicked to call the contextual menu and my index swiftly copied the selection. Time saved: 0.0005 seconds. Repeated several hundred times per day, this shortcut makes me more productive, hence making better use of taxpayers' money.
Old dog. New trick.
