While I agree that designating what a user can accomplish on your page is making UX sacrifices, this is handy:

Ctrl (Cmd) + Left click = open link in new tab

So we then have to learn the shortcuts for all of a browsers right-click menu options?

Not to mention the fact that a lot of add-ons add functionality to that menu.

But how long before someone figures out a way to override ctrl+clicks and middle-clicks with a lightbox as well?

Clicking with the mouse wheel usually does that

wow, you just made my day. thanks!
