Unless I missed it, no one addressed this issue.

I also got my first Mac recently. I bought a mini two weeks ago. Overall I like it, but this is one of the more annoying things for me. I use these keys constantly in Windows, as well and pressing CTRL + Left Arrow to be able to move back one word in a sentence while I'm typing. The Mac doesn't react the same way.

Are there equivelant keys combinations in OS X? What about a way to map my keystrokes to match what I expect them to do?
