how to know which actionbar im on?

[Poyzon]

Put your mouse over something and then run this macro. It will tell you the internal name of the object your mouse is over.

/run local f = GetMouseFocus(); if f then DEFAULT_CHAT_FRAME:AddMessage(f:GetName()) end

I don't have the macro command to get what keys are bound to that object. Take the name you got from above and look through your Key Bindings dialog in the WoW system menu.

Create a macro and place the macro in the button you want the name of. When you press the button, the name will show up in the chat window.

/run print(GetMouseFocus():GetName())
