How can I assign A to left-click on the mouse?

I want to use the sword in Ocarina Of Time with the left click on the mouse, but how can I do that? I try to do it with the marco modifier, but it wont let me assign it.

I managed to set it to the right-click button, I had to set the input controller plugin to Direct-Input. Not the left-click worked, I just had to hold it down some seconds and not just click. Then it assigned it. Bye bye X button.
