Draw a rectangle in illustrator, now before releasing your mouse, there is a keyboard if you keep you can make the shape repeat while you move the mouse. The result is a path of rectangle like an abstract art. Please tell me what keyboard is that.
Why not just try it out?
By 'keyboard' I assume you mean 'key.'
You're probably referring to the tilde (~) key. Should work the same on Mac and Win and in most AI versions. Also try it with modifiers keys (Shift, Alt/Option, etc.).
