I've seen the following focus macro floating around the Internet to improve my PvP play:
/cast [modifier:shift, target=focus] Spell; Spell
My question is, how does this get used? Say I have a target clicked on, and their frame shows up as my target frame. Then another enemy player shows up right besides them. What does focus do exactly? How can I use it to improve my gameplay?

This is the focus macro I currently use:
To use this, you must have the target you want as your focus targeted when you hit the button. After using it, you will then target whatever you were targeting before the focus target. For example:
The name of a specific enemy or target can be placed after "/focus" as in:
If you know the name of what you want focused for a certain fight, you can have this ready and get rid of Step 3 in the previous list.
As dlanod said, a focus gives you another health bar on your screen to monitor. When using a focus, you can be fighting one thing while still paying attention to something else in a fight. There are quite a few situations where this is useful.
In PvE:
In PvP:
There are of course other ways to employ your focus, but this is the general outline. Not everyone and not every class benefits from using a focus as much as others.
