These are some of my most used keyboard short cuts  Syntax aware selection in the editor selects a word at the caret and then selects expanding areas of the source code  For example  it may select a method name  then the expression that calls this method  then the whole statement  then the containing block  etc   Ctrl W  Basic Code Completion  to complete methods  keywords etc   Ctrl Space  Go to Declaration  Use this to navigate to the declaration of a class  method or variable used somewhere in the code  Ctrl B  Introduce Variable Refactoring  to create a variable from an expression  This expression may even be incomplete or contain errors  Since version 8  IDEA intelligently selects a likely expression when no text is selected  Ctrl Alt V  Go to Class  to quickly open any class in the editor  Ctrl N  To open any file  not just classes  Ctrl Shift N  Comment Uncomment current line or selection  Ctrl   and Ctrl Shift    Quick JavaDoc Popup to show the JavaDoc of the method or class at the text cursor  Ctrl Q  Ctrl J on Mac OS X   Smart Type Completion to complete an expression with a method call or variable with a type suitable in the current Context  Ctrl Shift Space  Rename refactoring to rename any identifier  Can look in comments  text files and across different languages too  Shift F6  Select in Popup to quickly select the currently edited element  class  file  method or field  in any view  Project View  Structure View or other    Alt F1  Highlight Usages in File  Position the text cursor on any identifier without selecting any text and it will show all places in the file where that variable  method etc  is used  Use it on a throws  try or catch keyword to show all places where the exception is thrown  Use it on the implements keyword to highlight the methods of the implemented interface  Ctrl Shift F7

Here are the Intellij IDEA keyboard shortcuts I find most useful  listed in roughly the order of usage for me    The shortcut I use the most is Ctrl   B  Go to declaration   to see what a method does  where a variable is declared etc  This is almost always followed by Ctrl   Alt   Left to get back to where I was  Ctrl   Alt   Right works to    go forward    again    A related navigation shortcut is Ctrl   Alt   B   Go to implementation   Press it when the caret is at the method name of an interface  and you get a pop-up list of all the places where this method is implemented  and you can select which one you want to go to  if there is only one implementation  you go straight there   The same goes for overridden methods   The opposite of this is Ctrl   U  Go to super-method super-class   If the caret is at the implementation of a method in an interface  indicated by the little green interface-symbol in the left gutter   this shortcut takes you to the interface itself   When I want to see all the places where a method or variable is used  which I want to do a lot   I use Ctrl   Alt   F7  Show usages   This gives you a pop-up list of all the usages  and you can easily navigate to each one  I prefer this over Alt   F7  Find usages   which gives you the same information  but in a separate pane below   To find classes  I use Ctrl   N  Go to class   which lets you search using only the capital letters in the class name     camel humps      and   as wildcard   Yet another shortcut I use  both when reading and writing code  is Ctrl   P  Parameter info  at the arguments of methods and constructors  to see the types and names of the parameters   When it comes to writing code  I use Ctrl   space  Basic code completion  a lot to auto-complete method names  variable names etc  or simply to see which methods are available for a certain object  by trying to auto-complete directly at the dot following the name of the object    For searching in the current file I use Ctrl-F  Find - probably the least surprising shortcut in this list   F3 Shift   F3  Find next previous  to repeat the search  and Ctrl   Shift   F  Find in path  to search in the whole project   Ctrl   W  Select successively increasing code blocks  is handy when selecting chunks of code  Repeatedly pressing it selects more and more of the code  Useful when searching  indenting  commenting out code etc   If there are errors in the file  F2 Shift   F2  Next previous highlighted error  will jump to them   I use the sequence Alt   C  N  Show Changes View  to see which files in the project I have modified compared to the subversion repository  To diff the current file against the version in the subversion repository  I use the sequence Alt   C  S  Y  Compare with the Same Repository Version   In the diff view  I use F7 Shift   F7 to navigate between the changes   When not in the diff view  I use Ctrl   Shift   Alt   Up Ctrl   Shift   Alt   Down to jump to the parts of the file that have been changed compared to the checked-out version  At each modification point  you see the corresponding part in the checked-out version in a pop-up window   Finally  I run JUnit tests using Ctrl   Shift   F10   Edit  One really useful shortcut that I ve only started using in the last few months is Ctrl   E  It brings up a pop-up with the 15 most recently used files  and you just arrow down to the one you want and hit enter to navigate to it

One of my real favorites may not count as a keyboard shortcut exactly  But the  iter  smart template is really great   basically if you want to iterate though something using a for loop type  iter  then tab to use the live template  itertab  it will figure out the most likely variable you want to iterate over and generate a for loop for it  I m pretty sure it uses the nearest reference to an object which supports iteration
