My q is similar enough that I don't think it warrants a new thread.
What about two mouse clicks simultaneously? I'd love to have mission control mapped to left+right click, but I'm not sure it's possible. There's no way to use right click as a modifier for the left click, is there?
I don't use a mouse and honestly don't know why you would want to do that when there are so many easier options. But what should theoretically work is this.
set a cycle action to cmd down/up (or another modifier). Trigger: for example, right click.
set "mission control" (predefined action) to left click with cmd down.
If you now execute a right click and then a left click "mission control" is activated.
