- Personally, I always have trouble with the little arrow spin-bar things
- myself.
-
- Your comments remind me of the old observation that, when drawing
- diagrams of computer memory addressing maps, it seems to be customary
- to put the high addresses at the TOP. When drawing small data structures
- and pointers and things, it's customary to put them at the BOTTOM.
- Generally, hardware people tend to think of high addresses as being at the
- top, software people think of them as being at the bottom.
-
- I've observed that when posed questions like "Is '2' above or below '3',"
- "What color is the letter Z," "does salt taste hotter or colder than
- sugar," etc. a remarkable majority of people are able to give very fast,
- completely assured answers. Followed immediately by a double-take as they
- are perplexed by their own ability to answer such a question.
-
- What's also interesting is that some of these things are not just training.
- There are certain features, those "up" or "down" arrows being one of them,
- that I have now been using almost daily for eight years, and still get
- wrong.
