Shortcut tutorial
I just got an iMac, my first, after many windows machines. I discovered by guessing that I could open a new browser tab in Safari by hitting [command]t. I'm sure there are all kind of cool shortcuts like this, not just for Safari. Where can I learn about them? There surely must be some pointers about the OS and UI that would be useful to someone migrating from the windows world. I looked at the tutorials and manuals listed on the support site, but I don't see anything that looks like it's going into any depth. Suggestions?
iMac, Mac OS X (10.7.4)
