for the mac the documentation says ctrl+click is equal to right click and option+click is middle click. It works fine using them with acme, but I cant seem to make a new window in rio?
for right click, you want command+click, not control+click. works here, and is the same in 9vx. You can fake a 1+2 or 1+3 sweep by sweeping without any modifiers and then tapping option or command. the 1+[2,3] copy method works fine too. i don't believe you can emulate the 2+1 chord using a one-button mouse. like eric said, though, you'll do better with a real three-button mouse.
