A Munchkin is the sort of person who, faced with a role-playing game, reads through the rulebooks over and over until he finds a way to combine three innocuous-seeming magical items into a cycle of infinite wish spells. Or who, in real life, composes a surprisingly effective diet out of drinking a quarter-cup of extra-light olive oil at least one hour before and after tasting anything else. Or combines liquid nitrogen and antifreeze and life-insurance policies into a ridiculously cheap method of defeating the invincible specter of unavoidable Death. Or figures out how to build the real-life version of the cycle of infinite wish spells.
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.
What's a "bucky key"...? (Edit: I see you were referring to this probably. Interesting, hadn't heard the term before) Anyway, there are several layout issues. I'm pretty picky when it comes to keyboard layout. Um, let's see. Correct number and layout of modifier keys (Control Option Command Spacebar Command Option Control; anything else is incorrect); correct numpad layout (18 keys, not 17, with Enter and 0 being the only two large ones); presence of volume control and eject keys above the numpad; shape of Return key (one-row height, not two-row); a properly sized backslash key... that ought to mostly cover it, I think.
I'm talking about the feel of the keyboard when I say that I prefer mechanical key switches.
As for what a gaming keyboard adds, I'm not the one who brought it up; wadavis mentioned them in this comment, citing extra keys to which macros might be bound. I've never used such a keyboard myself, I was just curious whether such a one might exist which would also fulfill my other criteria for a keyboard.
If all you want is programmable macros, then something like the Nostromo or Orbweaver could serve you well; every button and each direction of the 8-way hat switch can be changed to any input or macro possible from a USB device, including mouse clicks, multimedia commands, launching programs, or changing its own settings.
If your typical workflow can be reduced to 15-230 macros that you can keep straight, it could replace the keyboard as a primary input device. If you would benefit from 15-20 macros that you need to take a hand away from the keyboard to execute, it could serve as a useful addition. If you just want a keystroke combination that executes a series of commands, that's probably better done in software.
