If you're using one of the new MacBook Pros, then you can go to System Preferences - Trackpad and change the secondary click to use two fingers, bottom right corner, or bottom left corner of the trackpad.
Or you can always set it to right click by using two fingers. That's what I use and I find it's the most convenient instead of moving to a corner to copy/paste.
