Keybindings Layout
I made a table to help me map my shaman triboxing hotkeys, as I already had a 70 shaman, and they are plain and simple, of course, solo. So writing the table was needed to help me put keys to focus:
- Most important actions with just one hand;
- Long cooldowns / less used / less important to not use fast actions keys.

Interesting this took me a lot of time (interesting because I already have 4 70s, but mapping keys for multiboxing was so hard!), and I was very curious to see some "old school" boxer hotkeys and I couldn't find, just a screenshot here and there. From this comes my idea of sharing a layout, so others can get some use of it.

The table is attached, check below (sorry for the trash layout of it).

Macros
First thing, I play "focus", I like it more than focusless/leaderless, so the first button I press after grouping is the "All Smash In One", this is also an emergency macro if a slave is taking long to assist focus (due to lag), someone dies (then I can fast switch leader), or casting something I don't want anymore.
Code:
/focus [target=party1,nodead][target=zuldrek,nodead][target=zuldrok,nodead][target=zuldrik,nodead][target=player]
/assist [target=focus, exists]
/stopcasting
Attack Macros (then change to Chain Lightning, Frost Shock, etc)
Code:
/assist [target=focus, exists]
/cast Lightning Bolt
For Earth + Flame Shocks:
Code:
/assist [target=focus, exists]
/cast [nomod] Earth Shock
/cast [mod:shift] Flame Shock
Healing Macro (the last line with ctrl, is a "spread out" Chain Heal. Each slave is focused in one person, until everyone fills all names, and then when I press CTRL+Healing Macro, everyone cast chain heal in different players).
I also have 3 of those, as seen in the table. One for each member of the party, just changing the name.
Code:
/cast [target=Zuldrek,nomod] Lesser Healing Wave
/cast [target=Zuldrek,mod:alt] Healing Wave
/cast [target=Zuldrek,mod:shift] Chain Heal
/cast [target=focustarget,help,mod:ctrl][target=Zuldrik,mod:ctrl] Chain Heal
