Yesterday all the groups under my group's director (my boss's boss) met for an annual meeting to discuss statistics, politics, arbitrary administrative tasks, and a small bit of what I quaintly refer to as "real work". Like all such meetings, it started off with a "safety tip". This is where people with no medical, structural engineering, or injury prevention training give you unsolicited advice on how to behave both at work and at home, as though they were some sort of authority.
The tip this time was about hand injury prevention, and, although I find the whole "safety tip" phenomenon lame at best (dangerous at worst), this one was pretty sensible. Use the right tool - a crescent wrench is a bad hammer, for example. Most injuries occur to your off hand, e.g., you hammer the hand holding the nail. And lastly, the reflection-inducing question: How much of your job could you do if you lost a finger? A thumb? A hand? As in, we type for money, we dial phones, we take notes, we draw on whiteboards, we sometimes wear shirts with buttons. Hands and fingers are pretty useful for all these tasks. This got me reflecting on some fun keyboard related things I've done over they years.
As members of CompuServe's tech support group, my ex-wife and I (we were engaged at the time) did a lot of case note entries. This is where you summarize what a caller's problem was, what you did to try to fix it, and where the problem stands now. In some cases, a caller has only one phone line, and can't connect to the service while talking to you, and after the call ends, you must take the next call in queue rather than call back later to check on them. Although this is a rule I broke frequently, most tech support people gave the customer the boot happily, and hoped that the customer would get another CSR when they called back saying the problem still wasn't fixed. "Here, try this init string..." flush! "Sometimes that goes away if you reboot..." flush! That sort of thing.
