General Macro Help - Focus and Mod Question

[Cogglamp]

So I use a lot of modifier macros (primarily utilizing shift), but I've run into the issue where I'd like a little more functionality from my macros and need some help to see if what I'm thinking is even possible. Any help would be greatly appreciated.

Here's what I'm looking for:

Mage Example:

I have Spellsteal and Counterspell currently in one modifier macro so I've got it as follows:

#showtooltip
/cast [mod:shift] Spellsteal; Counterspell

What I'm looking for is being able to set a focus and be able to Counterspell the focus if I have a focus. If I don't have a focus, then it would default to Counterspelling my current target. All of that plus being able to use Spellsteal through a modifier. Is this possible? If so, how would I go about writing it?

Do you want the macro to set the focus? If not, something like this should do what you want:

#showtooltip
/cast [mod:shift] Spellsteal; [@focus,harm,nodead][] Counterspell
