title: How to see JavaDoc in IntelliJ IDEA?
body: <p>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 - <kbd>command</kbd>+<kbd>J</kbd>, 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. I need to at least know what type a method returns.</p>
