New Multiboxer - Key Mapping & Macros

[Osborn]

Hey there, I'm new to multi boxing and I've got some questions, some which may have been answered elsewhere (I'm a tiny bit over flooded with information, so I was hoping to get some guidance in form of where I should specifically look.)

I've so far level up 5 mages to 15 and 5 hunters to 10, no problems. I understand the basics. I've also looked at some of Mirai's videos and it has helped me allot, but I believe key mapping is still a rather big issue for me to understand.

When I first decided to try out multi boxing, I created a team of 3 casters, 1 healer and a tank. Worst decision in my life, because I've yet to figure out how to work this out. I found 5 of the same class being the easiest, as I press 1 button and it does the same spell on all characters judging that I've got them set in the same skill bar.

Now, I'm really interested in changing 2 of my hunters into a prot paladin and a perhaps holy paladin or holy priest, but then I end up with the same problem as before, 1-9 on the skill bar isn't going to be sufficient to organize the spells on all characters. Is there a way to expand this and bind hotkeys for new spells on each character? I assume it has to do with key mapping and if it does, I was hoping someone could send me in the direction of a noob friendly beginner's guide.

As far as it goes for macros, I've literally got none setup I think, apart from whatever ISBoxer's setup wizard did. Is there a noob friendly guide for this too? I assume creating macros could help me with the problem of 1-9 not being enough, and I read somewhere about gnome sequencer but I wasn't really sure how it'd work with ISBoxer.

Lastly, I assume this has to do with key mapping as well - First, if it's possible, how can I make my characters stop following me in combat? Sometimes I move to re position myself, and my characters end up stopping whatever they're doing i.e. challenging a spell only to move after me. Now secondly, is there a way for me to press something to make my "slaves" turn towards the target? I've had situations where I almost end up dying because my "slaves" aren't facing the target properly, resulting in them doing jack shit. EDIT: I figured this one out, I binded "turn left and turn right" which should help me, if there's a more efficient way of doing it, do let me know!

Thanks in advance for the help.

Ps. I'd appreciate some general direction guidance in where to look for healing setups etc. I just want to try and get through lower level dungeons with a team!
