Is there anything that is a software that integrates into windows (NOT MACRO) Dont need Macro programs, that click another button the same time I click my left click or certain buttons?
Example:
When I left click it will ALSO click 6 not just click 6 and not mouse click.
or
When I press 4 it will ALSO press 6, not just 6 and not press 4.
I need it for a combo I am working on. And no, it is not against the rules of the game I play to rebind keys. Any help is very very very much appreciated

It can be Pay or Free, just has to work, on windows 7.
