The keyboard is irrelevant if you don't look at the keys, it's the keyboard layout that's relevant, and that's a software setting. I was very confused the first time I used a computer whose keyboard layout had been changed to Dvorak.
But there is something of a problem if you share a computer with someone who uses Qwerty, I guess. Switching back and forth might get annoying (although maybe you can set an AutoHotKey to do it?).
No need for AHK, layout-switching shortcuts exist in every operating system I've used.
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
