Make Intellij Documentation (quick-doc) Window Close When Mouse Is Moved Away

In Eclipse, when you hover over a variable, method, etc, you get a pop-up window with the documentation. When you move the mouse off of it, it disappears. I can simulate the first

Solution 1:

Found out how to do it - just click the big red cross on the task bar - NOT the usual one to close a window in the top-right.

Solution 2:

Uncheck the Autopopup documentation in(ms) option from Preference-> code completion

Try changing the Documentation mode- it is also useful (uncheck floating mode)
