I don't have a right button on my McBook Air. Can I still separate blocks in Minecraft?

I do not have a right button on my computer, but i still wanna craft. Is it possible? And can I right click? I've tried and it doesn't work.

Either connect a mouse to your computer, or ctrl-left click will act as right click in 1.6.2 (horse update) and above.
