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.
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 shortcuts 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 developer and Java web application developer 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 which has a complex code, I often need to find classes with the just blink of the eye and this eclipse keyboard shortcut is just made 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 that it can find out not only Java files but any files including XML, configs, and many others, but 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 which can fix up any error for you 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
Another Eclipse keyboard shortcut for fixing missing imports. Particularly helpful if you copy some code from other file and what to import all dependencies.
Eclipse Shortcut for Quick Navigation
In this section, we will see some eclipse keyboard shortcut which helps to quickly navigate within the file and between 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 class in 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 program in Eclipse is also a skill. There are so many debugging tools and features available in Eclipse, which many Java programmer doesn’t know e.g. conditional debugging, hit count and remote debugging.
Eclipse Shortcut for Editing Code
These Eclipse shortcuts are very helpful for editing code in Eclipse:
5) Ctrl + / for commenting, uncommenting lines and blocks, see here for live example.
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
Miscellaneous Eclipse Shortcuts
These are different Eclipse keyboard shortcuts which doesn’t fit on any category but quite helpful and make life very easy 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 which means we are going backward.
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 issue while using these Eclipse shortcuts in any particular version of Eclipse IDE.
