How to enqueue techs on Endless Space?

If I choose some future advancement which has its prerequisites not yet researched I will enqueue more than one tech. Can I enqueue unrelated techs? How do I do it?


One must Shift + Left Click each in turn to queue up each technology in turn. Without shift, it will reset the queue each time you click on a new technology.

I searched through the Endless Space manual on Steam and I couldn't find a reference to this, but it is discussed on forums.
