Q:
Multiple Mouse Clicks Macro
NO you CANNOT. It’s been stated several times in several threads, and what players are saying IS the official answer. One click, one action, that’s it. Anet decided to add an exception in the form of “sheet music” for instruments, but that is the only exception.
what most people seem to do is bind clicks to mouse wheel to make it a lot less (literally) painful to open stacks of stuff while still trying to stick to the one press to one action rule.
Of course if the UX guys at ANet could just add a right-click use all menu option none of this would be needed.
