Whoops, sorry, I was seeing what worked and what didn’t.
I just found out that tab in most web browsers doesn’t insert a tab, it takes you to the next active control, which happened to be “Submit Reply”, and space just happens to trigger it.
As I was saying: Capslock and numlock work as advertised. Pgup/pgdn and “home” work too. The “help” button doesn’t seem to do anything. Delete works as a windows “backspace”, but since the “clear” key is numlock under windows, there isn’t anything on this keyboard that behaves like a windows “delete” key. However, the Apple Pro Keyboard does have a delete key, it looks like.
Oh, one thing is that the apple/windows key and the option/alt keys are in reverse order to most windows keyboards.
When I plugged it in, plug n’ pray recgonized it as an “Apple USB Keyboard” and gave it a generic HID driver. It also recognized the keyboard as a hub, as it has two unpowered USB ports on it.
I really don’t see anything mechanically different from this and my newer PC keyboards, as they’re all membrane type keyboards.
One thing that I think may make a difference in feel is that the Mac keyboard’s key bed (the bottom, where the keys get mounted) is actually curved slightly, rather than flat. So even with your hands in position over the home row, your fingertips come straight down on all the keys, rather than at an angle for the ones off the home row.
Also, I think the throw (how far the keys need to be pressed) is slightly shallower than either my HP or Logitech (which I suspect were both made by Logitech) pc keyboards, but I don’t have anything to properly measure that with.
Because of the lack of a delete key, I don’t think the older, little iMac keyboard would make a good PC keyboard. Though I think the new Apple Pro Keyboard probably would work well, but I’d want to test out the delete key first.
