Index Help Menu 

Help on Keyword

Shortcut: CtrlF1

Searches the word around the caret in the help index files of the JDK and displays the search result in a list. Selecting an item from the list will load the corresponding help topic. If the Quick search text field owns the input focus, then the word around the caret position will be taken from this field. This is a useful technique for looking up a help topic without changing the editor content.
