On Mac OS X, you can right click by holding down control and clicking. I swapped the command and control keys with
setxkbmap -option altwin:ctrl_win, but how do I make it right click by holding down control and clicking? I am on a Powerbook G4 with Debian XFCE.
Chris Down's answer requires you to press control and click at exactly the same time. On Mac you can hold down control and click.
