1. Shortcuts

Using shortcuts make a developer more productive. Eclipse provides keyboard shortcuts for the most common actions. Using shortcuts is usually preferable as you can perform actions much faster.

Eclipse supports of course the typical shortcuts, e.g. Ctrl + S for saving, Ctrl + C for copying the selected text or file and Ctrl + V for pasting the element currently in the clipboard.

This description uses the shortcuts based on Windows and Linux. Mac OS uses the Cmd key frequently instead of the Ctrl key.

The Ctrl + 3 shortcut allows you to perform all available actions in Eclipse. This shortcut puts the focus into the Quick Access (quick access) search box which allows you to execute any Eclipse command. For example you can open a Preference , a Wizard , a view and a Preference page.

You can also use QuickAccess to search for an opened editor by typing in the name of the resource which the editor shows.

The following screenshot shows how you the available commands in quick access for the "New Java" search term.

The following shortcuts are the absolute minimum a developer should be familiar with to work efficient in Eclipse.

Want to learn more about keyboard shortcuts in java. check out this tutorial of 30 different shortcuts you can use with eclipse ide..

Join the DZone community and get the full member experience.

This tutorial is about 30 Eclipse keyboard shortcuts , this list is by no means complete and I will suggest you guys share eclipse shortcuts listed other than here to make this more useful. Eclipse is the most used Java development IDE and knowing Eclipse shortcuts not only improve your productivity but also makes you more efficient. You will have more time for things you like to do. Using keyboard shortcuts also helps to impress colleagues and shows that you have a good hold on tools you used for Java Development. If you are a Java developer, who use Eclipse as your main IDE for all-purpose e.g. coding, development, and debugging, then I also suggest you take a look at Beginners Eclipse Java IDE Training Course, one of the best course to learn how to use Eclipse effectively from Java programmer's perspective.

I was a big fan of Netbeans IDE before coming across Eclipse because I was from the J2ME background and Netbeans provide sophisticated IDE environment to enable you to build, debug and run your Java application in various mobile emulator including some advanced processing options e.g. preprocessing, setting up Exception breakpoint etc.

From that time I love to know keyboard shortcuts on IDEs and other tools, I used for development including Edit Plus, Microsoft Excel etc. Knowing your tool better certainly helps you to deliver more in less time and find something really quick when a production issue arise.

As I said, I was a NetBeans fan at the start of my career but hen I joined an investment bank I came across Eclipse IDE, since everybody in my team is using and Netbeans IDE was not available in company (don’t know why that was not allowed net-beans even though it was free) I have decided to go Eclipse way.

Later I found that Eclipse was most suited for that distributed core Java application which runs on Eclipse and depends upon a proprietary Linux library. It wasn't possible to run the whole application in Windows and that time some of the cool features of eclipse e. g. Remote Debugging, Conditional Breakpoints, Exception breakpoints, and Ctrl+T and Ctrl+R kind of shortcuts really saved my life.

Here I am sharing a list of 30 Eclipse keyboard shortcut s which I found most useful and used in my day to day life while writing code, reading the code or debugging Java application in Eclipse.

30 Useful Eclipse Keyboard Shortcuts for Java Programmers

Here is my list of 30 chosen Eclipse IDE keyboard shortcuts for Java developers. It's useful for both core Java developers and Java web application development using Eclipse IDE for web development.

1) Ctrl + Shift + T for finding class even from jar

This keyboard shortcut in Eclipse is my most used and favorite shortcut. While working with a high-speed trading system has a complex code, I often need to find classes with the just blink of the eye. This eclipse keyboard shortcut is made just for that. No matter whether you have class in your application or inside any JAR, this shortcut will find it.

2) Ctrl + Shift + R for finding any resource (file), including config XML files

This is similar to above Eclipse shortcut with the only difference being that it can find out not only Java files but any files including XML, configs, and many others. However, this eclipse shortcut only finds files from your workspace and doesn’t dig at the JAR level.

3) Ctrl + 1 for quick fix

This is another beautiful Eclipse shortcut that can fix up an error in Eclipse. Whether it’s missing declaration, missing semi-colon, or any import related error, this eclipse shortcut will help you to quickly sort that out.

4) Ctrl + Shift + o for organize imports

This is another Eclipse keyboard shortcut for fixing missing imports. This is particularly helpful if you copy some code from another file and import all dependencies. You can see the Beginners Eclipse Java IDE Training Course to learn more about code formatting shortcuts in Eclipse.

Eclipse Shortcut for Quick Navigation

In this section, we will see some Eclipse keyboard shortcuts that help us to quickly navigate within the file and between the file while reading and writing code in Eclipse.

7) Ctrl + o for quick outline going quickly to a method

9) Alt + right and Alt + left for going back and forth while editing

12) Alt + Shift + W to show a  classin    package explorer

13) Ctrl + Shift + Up and down for navigating from member to member (variables and methods)

15) Ctrl + k and Ctrl + Shift +K for find next/previous

16) Go to a type declaration: F3 , this Eclipse shortcut is very useful to see function definition very quickly.

Apart from these keyboard shortcuts, learning how to debug Java programs in Eclipse is also a skill. There are so many debugging tools and features available in Eclipse, which many Java programmer don't know about, e.g. conditional debugging, hit count, and remote debugging.

If you really want to become a good Java developer, I suggest you improve your debugging skills. If you need some help, Eclipse Debugging Techniques And Tricks is the best place to start with.

Eclipse Shortcut for Editing Code

These Eclipse shortcuts are very helpful for editing code in Eclipse:

5) Ctrl + / for commenting, uncommenting lines and blocks

6) Ctrl + Shift + / for commenting, uncommenting lines with block comment, see here for example.

8) Selecting class and pressing F4 to see its Type hierarchy

10) Ctrl + F4 or Ctrl + w for closing current file

11) Ctrl+Shirt+W for closing all files.

14) Ctrl + l go to line

16) Select text and press Ctrl + Shift + F for formatting.

17) Ctrl + F for find, find/replace

18) Ctrl + D to delete a line

19) Ctrl + Q for going to last edited place

You can see this free course on Udemy called Eclipse IDE for Beginners: Increase Your Java Productivity to find live examples for most of these shortcuts.

Miscellaneous Eclipse Shortcuts

These are different Eclipse keyboard shortcuts that don't fit on any category, but they can be quite helpful while working in Eclipse.

20) Ctrl + T for toggling between supertype and subtype

21) Go to other open editors: Ctrl + E .

22) Move to one problem (i.e.: error, warning) to the next (or previous) in a file: Ctrl +. For next, and Ctrl +, for the previous problem

23) Hop back and forth through the files you have visited: Alt + ← and Alt + →, respectively

25) CTRL+Shift+G , which searches the workspace for references to the selected method or variable

26) Ctrl+Shift+L to view the listing for all Eclipse keyboard shortcuts

27) Alt + Shift + j to add Javadoc at any place in Java source file

28) CTRL+SHIFT+P to find closing brace. Place the cursor at the opening brace and use this.

29) Alt+Shift+X, Q to run Ant build file using keyboard shortcuts in Eclipse

30) Ctrl + Shift +F for autoformatting

Remember, we are technical people. If we are not learning, we are going backwards.

And, here is the nice image to remember these useful Eclipse shortcuts for Java programmers :

If you have some more useful Eclipse keyboard shortcuts then please post as comments, I will include them in this list. These Eclipse shortcuts will mostly work almost all Eclipse versions, e.g. 3.5, 3.6 Helios, Eclipse Ganymede and Indigo. Let me know if you face any issues while using these Eclipse shortcuts in any particular version of Eclipse IDE.

Key Strokes, Key Sequences, and Key Bindings

A 'key stroke' is the pressing of a key on the keyboard, while optionally holding down one or more of these modifier keys: Ctrl , Alt ( ⌥ on macOS), Shift , or ⌘ (only on macOS.) For example, holding down Ctrl then pressing A produces the key stroke Ctrl+A . The pressing of the modifier keys themselves do not constitute key strokes.

A 'key sequence' is one or more key strokes. Traditionally, Emacs assigned two or three key stroke key sequences to particular commands. For example, the normal key sequence assigned to Close All in emacs is Ctrl+X Ctrl+C . To enter this key sequence, one presses the key stroke Ctrl+X followed by the key stroke Ctrl+C . While Eclipse supports key sequences of arbitrary lengths, it is recommended that keyboard shortcuts be four key strokes in length (or less).

A 'key binding' is the assignment of a key sequence to a command.

A 'scheme' is a set of bindings. Eclipse includes two schemes:

• Emacs (extends Default)

The Default scheme contains a general set of bindings, in many cases recognizable as traditional key sequences for well known commands. For instance, Ctrl+A is assigned to Select All , and Ctrl+S is assigned to Save .

The Emacs scheme contains a set of key bindings familiar to users of Emacs. For instance, Ctrl+X H is assigned to Select All , and Ctrl+X S is assigned to Save .

It is important to understand why the Emacs scheme says that it 'extends Default'. The Emacs scheme is not a complete set of bindings like the Default scheme. Rather, it borrows from the Default scheme where possible, only defining explicit Emacs-style bindings where they vary from the Default scheme. Generally, only well known commands like Select All , Save , etc. have specific Emacs key sequences associated with them.

Choose the scheme you are most comfortable with by changing the 'Scheme' setting on the keys preference page. If you choose the Default scheme, all Emacs bindings are ignored. If you choose the Emacs scheme, explicit Emacs-style key sequence assignments take precedence over any conflicting assignments in the Default scheme.

Key bindings can vary based on the current context of Eclipse.

Sometimes the active part might be a Java file editor, for instance, where a different set of key sequence assignments may be more appropriate than if the active part was an html file editor. As a specific example, typically Ctrl+B is assigned to Build in a context such as Java file editing, while Ctrl+B is assigned to Make Text Bold in a context such as HTML file editing. This context is usually determined by the active part, but it can be influenced by the active window or dialog as well. If the active part does not choose a particular context, the workbench will set the active context to In Windows .

Eclipse includes a number of different contexts. Some examples are:

• In Dialogs and Windows
• In Windows (extends In Dialogs and Windows)
• In Dialogs (extends In Dialogs and Windows)
• Editing Text (extends In Windows)
• Editing Java Source (extends Editing Text)
• Debugging (extends In Windows)
• Debugging Java (extends Debugging)
• Editing Ant buildfiles

Much like configurations, contexts can extend other contexts. For example, the Editing Java Source context borrows key bindings from the Editing Text context, which in turn borrows key bindings from the In Windows context.

Note: It is not recommended to promote a key binding to a context which it extends. For example, it is not recommended to move an Editing Text key binding to the In Dialogs and Windows context. This may have unexpected results.

It is possible for some key bindings to work in dialogs. Those key bindings are assigned to the In Dialogs and Windows context. One example of such a key binding is the key binding for "cut". It is possible to change these key bindings. For example, it is possible to have Ctrl+X as cut in dialogs, but Ctrl+W as cut in windows.

Platform and Locale

Key bindings also vary by platform and locale. On the macOS platform, ⌘+S is assigned to Save , instead of the usual Ctrl+S . On Chinese locales (zh), Alt+/ is assigned to Content Assist , instead of the usual Ctrl+Space .

The current platform and locale is determined when Eclipse starts, and does not vary over the course of an Eclipse instance.

Customizing Key bindings

In this example we want to bind CTRL+5 to the About command. By default the keys preference page will show you all possible keybindings. You can see the About command listed in the Help category. You can bind the command by putting focus in the Binding text box and pressing CTRL and 5 like you would if you were executing the command.

When you type CTRL+5 you have created a binding for About. The right-most column will indicate that this is a user binding by displaying a U . If there was a conflict with another key, this column would also display a C . The binding will be in the default context, "In Windows". You can now use the When combo box to change the key binding context (for example, to move this binding to "Editing Text").

If you wanted to add a second key binding to About, you can use the Copy Command button to create a second command entry for you to bind another key to. If you want to delete a binding, you can either use the Remove Binding button or simply give focus to the Binding text box and hit Backspace .

The Dynamic Nature of Key bindings

Key bindings are provided by plug-ins, and in Eclipse, plug-ins can be added or removed. This can cause key bindings declared by these plug-ins to be added or removed. Eclipse stores custom key bindings in a way to compensate for this. Consider the example above where CTRL+6 was assigned to About in the Default scheme. Say you install a new plug-in that assigns CTRL+6 to a particular command. Eclipse will preserve your assignment to About .

Conflict Resolution

There are only a finite number of simple, common key strokes available to assign to a multitude of commands. We have seen that scheme, context, platform, and locale all partition key sequence assignments into domains where they don't conflict with one another. Consider the case for Ctrl+B above if contexts did not exist. One plug-in would assign Ctrl+B to Build , the other plug-in would assign Ctrl+B to Make Bold Text . How would Eclipse properly resolve this conflict?

Though conflicts are drastically reduced by employing the above mechanisms, they can still occur. Two plug-ins, independent of one another, could assign the same key sequence to different commands with the same context, scheme, platform, and locale. Consider if a plug-in assigned Ctrl+F4 in the In Windows context and Default scheme to one of its commands. This directly conflicts with Eclipse assigning Ctrl+F4 to the close command in the same context and scheme.

This is a conflict. It wouldn't be proper to invoke both commands, nor would it be proper to simply choose one of the two commands to receive the key stroke. We pop up the Key Assist Dialog with the conflicting commands and allow the user to select one. The Key Assist Dialog is the same dialog that displays command choices for multiple key stroke key bindings. For example, if 2 commands were bound to F12 you might see:

If the user sets a keybinding and creates a conflict, the conflicting bindings will be displayed in the conflicts list. This can be used to navigate between conflicting keybindings so that they can be changed.

These types of conflicts can be resolved by explicitly assigning the key sequence to one of the commands, or remove it from the other.

Another type of conflict can be caused by multiple-key stroke key sequences. For example, in the Emacs scheme, there are many multiple-key stroke key sequences beginning with the key stroke Ctrl+X . Ctrl+X K is assigned to Close . Ctrl+X H is assigned to Select All .

As previously mentioned, the Emacs scheme borrows key bindings from the Default scheme. In the default scheme, Ctrl+X is assigned to Cut . Though the Emacs scheme doesn't explicitly redefine Ctrl+X , pressing Ctrl+X is required as part of many of its key bindings. In the Emacs scheme, when one presses Ctrl+X , one is half way to entering one of many possible assigned key sequences. One would not expect the Cut action to be invoked at this time.

For this type of conflict, the rule is that the Ctrl+X key sequence assigned to Cut would be ignored. Otherwise, it would not be possible to complete many of the key bindings in the Emacs configuration.

Export Key Bindings

The bindings can be exported to a CSV file. For this purpose, press the button Export CSV ... . This will launch a file dialog, where you can specify the location of the export file. Note: The export file is for reporting purposes only and can not be used to import the binding files into Eclipse.

Show Key Bindings When Command is Invoked

For learning purposes, presentations or screen casts it is very helpful to show the corresponding key binding when a command is invoked. Whenever the command is invoked (via the keyboard or via menu clicks), the key binding, the command's name and description are shown on the screen.
