Adding javadoc to a method in IntelliJ - using keyboard shortcut

Introduction

The way to add Javadoc to a method in IDEA is to put the cursor above the method and write '/**' and press Enter.

In Eclipse you can use a keyboard shortcut to produce the same result. This can be emulated in IDEA!

Implementation steps

The first thing to do is to create a macro:

1. Start recording a a macro in Edit - Macros - Start Macro Recording
   
   1. Press Down
   2. Press Ctrl + Up
   3. Press ⌘ + Left
   4. Write /**
   5. Press Enter
2. Stop the macro recording in Edit - Macros - Stop Macro Recording
3. Give it a cool name
4. Edit the macro in Edit - Macros - Edit Macros, select your new macro and edit it to contain the following:
   
   1. Action: EditorDown
   2. Action: MethodUp
   3. Action: EditorLineStart
   4. Typing "/**"
   5. Action: EditorEnter

Now you can add a keyboard shortcut to the macro:

1. Double-click on your macro in Settings - Keymap - Macros - Your macro with the cool name
2. Choose Add keyboard shortcut
3. Press the keyboard combination that should trigger the macro, e.g. ⌘ + Shift + J

Result

You can now add javadoc to a method using a keyboard shortcut from anywhere within a method.
