A reasonable suggestion, though I find that the time required to bind the macros, then remember them, then remember to use them, is too much effort for me. That, of course, is up to personal preference.
Also: do you know of a gaming keyboard that is a Mac keyboard (presence of appropriate keys and layout) and has clicky-keys (a la the Apple Extended / Matias ProTouch Edit: got the name wrong, it's the Matias Tactile Pro)?
Das Keyboard now comes in a real Mac version (they used to just have exchangeable keycaps and it's never been quite ideal). It's clicky and nice. It doesn't have lunatic gaming 'features' like enormous rubber WASD though.
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.
