Hi all, this has probably been discussed, but I couldn't quite find what I need. I just bought an iMac after having been a happy MacBook user. The iMac keyboard has the following inconveniences for me: a) I miss the trackpad and I hate the mouse b) for the tilde character ~ I have to do Alt+n. Shift+~ produces the +/- character. I use ~ a lot for Unix command-line style stuff (strangely enough on my MacBook Shift+~ works fine). So I hooked up my nice IBM SK-8835 keyboard with trackpad and track stick (exact copy of a Thinkpad keyboard + numerical key). The iMac didn't recognize the IBM keyboard so at the prompt I choose standard US keyboard. Now I can type with IBM and the trackpad and track stick work perfectly. However of course it lacks the Apple key. Questions: 1. Can I remap the keyboard and use Alt instead of the Apple Key? How? 2. I'd like to keep both keyboards hooked up and I don't want to remap the MAC keyboard, only the IBM one. How do I do that? 3. can I remap the Mac keyboard so that Shift+~ produces tilde ? Thanks for the help.
