The Blind Macro
This macro is one of the more useful macros, but you need to use your brain to use it. What this macro does is uses Blind; it first checks to see if you have a focus target (use /focus or bind a key through the Key Bindings interface, or use Proximo to set it), and if you have a focus target, it will use Blind on that target. If you don’t have a focus target, it will Blind your current target.
The reason I say you need to be careful is because you will attempt to Blind your focus target no matter what with this macro, even if it’s dead or out of range. I strongly recommend having a /clearfocus macro handy when using this.

/cast [target=focus, harm, exists] Blind; Blind
And yes, you need both Blinds in there.
