It is all done with CSS. Changing removing elements from the print css. When you done the old, javascript
.click(function () {
window.print();
}
By the way they have used jQuery. Three cheers very well done!
I was willing to overlook it if he was just foppishly referring to option-click under the assumption that his ideal user would be using a Mac too, but no -- the functionality doesn't work with any of the modifier keys in any Gecko or Webkit browser on Linux.
