I just switched from Eclipse to IntelliJ. IntelliJ lacks one feature from Eclipse – when you put your mouse over a method, Eclipse shows javadoc info. I think the way to show it is to use a shortcut – command+J, but when I click it, I get something wrong as on the screen shot below. Please advise me on how I can quickly get javadoc information.

Yet another way to see the quick doc is on mouse move:
