Hi derek,
As Duncan mentioned, it is very useful when one wishes to type over existing text. However, this is a fairly uncommon wish in the typical GUI user environment, where the typist can highlight a group of characters and then begin typing. The highlighted characters disappear and the replacement is accomplished without changing the behavior of the keyboard. Many applications now attempt to guess what you want to highlight by performing the operation on words. To me this is not an advantage, for it often means that I delete one or more characters beyond what I wish. As Rolf noted, the adjacency of the Insert and Delete keys makes it far too easy to switch unwittingly to Insert mode. I sometimes wonder whether keyboard designers ever have to type, or whether they simply dictate their design inspirations into a microphone as some non-typists of my acquaintance do. When I received a new PC at work, some bright spark had placed an extra Backslash key next to the left Shift key _and_ reduced the size of the Shift key. After a few days of typing backslashes every time I wanted a capital letter, I popped both keys off and extended the Shift key to mostly cover the useless Backslash. I once programmed a special keyboard for a one-handed typist that allowed one to reprogram the meaning of keys, thereby accommodating
individual preference rather than the lumbering Frankenstein of the average user. Now that would be a worthwhile innovation.
