The shortcut I use the most is Ctrl + B (Go to declaration), to see what a method does, where a variable is declared etc. Here are the Intellij IDEA keyboard shortcuts I find most useful (listed in roughly the order of usage for me): Use it on the implements keyword to highlight the methods of the implemented interface: Use it on a throws, try or catch keyword to show all places where the exception is thrown. 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. Select in Popup to quickly select the currently edited element (class, file, method or field) in any view (Project View, Structure View or other): Can look in comments, text files and across different languages too: Rename refactoring to rename any identifier. Smart Type Completion to complete an expression with a method call or variable with a type suitable in the current Context: Quick JavaDoc Popup to show the JavaDoc of the method or class at the text cursor: Go to Class, to quickly open any class in the editor:Ĭomment/Uncomment current line or selection: Since version 8, IDEA intelligently selects a likely expression when no text is selected: This expression may even be incomplete or contain errors. Introduce Variable Refactoring, to create a variable from an expression. Use this to navigate to the declaration of a class, method or variable used somewhere in the 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.:īasic Code Completion, to complete methods, keywords etc.: Syntax aware selection in the editor selects a word at the caret and then selects expanding areas of the source code. If the previous one was for indenting the code, this one is for reformatting the code in all of its aspects, for the whole file, again based on the settings defined in Settings/Editor/Code Style.These are some of my most used keyboard short cuts The selection will be indented with the specified configuration in Settings/Editor/Code Style, for the language you are working with, in the “Indent” setting. and also with synchronized or Runnable blocks. This allows to surround the code automatically with control structures such as if, for, try/catch, etc. Similar to the previous one since the Object methods also appear ( hashCode, equals, etc.), but is also applicable for methods of extended classes.

The getters and setters, and also the constructor, are suggested based on the class attributes. Methods available to be generated automatically.
