How to change leader on the fly.

[Heli12345]

I have and idea for the focus-based system. What if I have it so the keys "Page Up", "Page Down", "Home", "End", and "-" all correspond to have it so when I press "Page Up", for example, they all focus on one character, in this case for "Page Up" they all focus on Heliasus. This would be macro based, with the setup like this:

/focus "InsertCharacterName"

Each key is set to focus on a different character, and when I need to change characters, I just press the key I need to press and switch windows, then apply my follow macro (based off focus) and the leader changes just like that. I had some problems setting this up though, as when I tested the macro, the character wouldn't focus. I'm not sure if this is a limitation within game or keyclone, or maybe something on my part. If someone could clear this up for me, that'd be great.

~~~EDIT~~~
I think my problem might be the macro itself. Instead of the one listed above, I might need:

/target "InsertCharacterName"
/focus target

Any and all feedback is greatly appreciated
