World-of-warcraft – Getting Spells IDs from WoW

WoW's macro system is deliberately unable to cast multiple spells with a single keypress except in very specific circumstances; this is to discourage botting/cheating. Blizzard's approach to macros (in-game or out) is that one keypress should trigger only one action.

The only case in which multiple spells/items can be used in a single macro is when only the last one triggers the global cooldown. This means that a warlock could macro Soulburn and Summon Felhunter together (because Soulburn doesn't trigger the GCD), but not Bane of Agony and Corruption. If you have many spells or items which don't trigger the GCD, you can even chain them together, as in the (in)famous PoM/Pyro macro for mages.

If you want to cast multiple GCD-causing spells with the same macro, you can use /castsequence to do it, but you'll need to hit the macro once for each spell. This can still provide plenty of flexibility even for fairly complex cast sequences, especially when combined with other macro commands and conditionals. I thoroughly recommend Wowpedia's page on Making a macro for learning how to create powerful macros.

I actually use bartender for this purpose. While I am unsure as to exactly what you mean by:

I have no way of telling what keyboard button my spells are with all of the stuff bartender adds.

I will try to describe how I do it with my mouse and my Nostromo.

First of all, Bartender can easily work with modifier keys, you simply enter key binding mode and press the combination (Alt-F) for example, and it will be bound.

I lay out my bars in whatever way I want them to look, put spells on the bars, and enter keybinding mode, hover over the button you want to bind, and press what you want - pretty simple.

Beyond that, you can do other things like hide the bars, or via the Razer configs map the mouse buttons to more standard keyboard buttons.
