If the number pad slash is not working as a left mouse click when you have the mouse pointer positioned where it should be with Golden Cursor, you can also use the "immobile mouse" trick. This is much easier to do if your system has an optical mouse, which you can tape over the laser source on the bottom that reads movement and still be able to move the mouse without it thinking it's moved. If it's an older mouse with a ball you can tape the mouse into place on your desktop out of the way somewhere, but be able to hit the actual left click and right click button when needed.

The psychology of adultery has been falsified by conventional morals, which assume, in monogamous countries, that attraction to one person cannot co-exist with a serious affection for another. Everybody knows that this is untrue. . .
~ Bertrand Russell
