I used to work at some place that could select a line of code, and by pressing "ALT + SHIFT + DOWN_KEY/UP_KEY", it would copy this line below or above respectively.
Now I work at some place else and this shortcut command does not work.
How can I enable it?
Are you sure it is ALT + SHIFT + UP/DOWN and not CTRL + ALT + UP/DOWN?
If I correctly understand your request, then what you need is to open the preference and go to General > Keys. Look for Copy Lines and Duplicate Lines.
You can use CTRL+ SHIFT+L to see a list of short cuts to check you remembering correctly.
Otherise you can customise/enble shortcuts using
Window --> Preferences --> General --> Keys
As I use Linux, I found the problem.
It has a shortcut registered. What you have to do is disable it.
Go to System, ShortCut Keys, then you remove the shortcut "CTRL+ALT+UP" and "CTRL+ALT+DOWN".
Done, it works.

I am aware of the Eclipse snippet "sysout" which is neatly replaced with System.out.println(); when tab-completed.
This is very useful but sometimes, I need to wrap some existing code in a System.out.println();
In Eclipse internals, the template is defined as being able to wrap a "selected word". But how can I use the snippet with selected text since typing "sysout" obviously removes the selected text.
Any idea?
The sysout template acts upon entire Java statements.
Highlight a statement in the editor.
Hit CTRL-SPACE (or whatever you have set up for content assist.)
Type sysout then hit enter. Note that when you're typing sysout it will temporarily overwrite your statement (but it will come back wrapped by System.out.println when you hit enter.)
Eclipse has "Surround Width" Option which can do this for you.
SHIFT + ALT + Z should get you that to see how that templates meta-data layout.
I don't think you can do it in one go, but what about cutting the selected text and then: tab+space, ctrl+v
it's just one key combination more.
if you use content assist (ctrl-space on Windows), at the end of the list will be the sysout option. you might want to augment the template with quotes around the word selection so you dont need to type them in.
Preference>General>Keys.
then search "content assist" or "content" in "type filter text".
don't press Enter.
choice "content assist".
type Binding and set your own shortcuts.
such as "control+space".
The main part is into:
Java->Editor->Templates
This can accessed by:
Preferences window: into Java->Editor->Templates.
Surrounding a text and press:
Windows: SHIFT + ALT + Z (as sadhasivam said)
Mac: CMD + OPT + Z
to display the Preferences Window
since 6 weeks i´m studying WI. Thats somewhere between business management and IT.
We´re using eclipse and i´m looking for a shortcut that allows to switch between the class-windows like alt + tab for Windows.... windows^^.
Thanks for help.
in tool bar go to Window>Preferences>General>key : change shortcut key as per your use and us can also fine another shortcut for eclipse.
I was searching for the same Shortcut.
I changed the class window accidently with a shortcut and then found out, that you can do it with tab + alt + right/left instead of alt + tab (changes the windows from Windows :D).
Make sure to tab + alt in a free row where no code is, as it will push the line to the right, because of the tab button.
Whoever will search for this.
You're welcome.
Use: Alt + Arrow Key Left/Right
currently in eclipse if i want to generate a constructor or getters/setters i
go the class name right click on that ->source->access the right Generation option
while in the android studio we have a convenient and fast shortcut to do that
i just need to press CMD+N anywhere in the page to open the generate dialog
is there an eclipse shortcut available that is equivalent to that ?
Press Alt+s then type c for constructor, r for set/get s for
toStringetc..
You can go to Windows -> Preferences -> General -> Keys to map this action to a shortcut of choice.
This is how to do it:
There isn't one by default, but if you wish you can modify the mappings and add a shortcut. You can do this by going to window->preferences->general->keys
Go in window -> preferences -> general -> keys
Type generate in the search bar.
Find Generate Getters and Setters
Click on the binding field and hit your custom shortcut (here : Ctrl + Alt + Shift + S).
Go to Windows -> Preferences -> General -> Keys or you can take the list of shortcut in this site 25 Eclipse Shortcut Keys
You can also use the quick fix : Ctrl + 1.
When you have an error, it allows you to resolve this error. and when the cursor is on a variable, it allows you to generate getter and setter.
If you want an empty construtor, just type Ctrl + space somewhere in your class.
Short answer: no.
But google shows a number of pages on how to do it, e.g. https://wiki.eclipse.org/FAQ_How_do_I_provide_a_keyboard_shortcut_for_my_action%3F
A lateral solution, but you may be interested to check out Project Lombok (I don't use it myself at the moment.)
As I remember ,alt + insert do this.
The answer by #Rustam put me on the right path.
but since his answer is based on windows version of eclipse and I am using mac i was unable to confirm it .
i added this answer to provide additional data for any one using the MAC version of eclipse
ALT + CMD + S will bring the source menu after that you can select the correct generation option

In a Visual Studio, you would use Ctrl+L, whereas in Eclipse I am forced to select a line or, if it is empty, go the beginning of the line before clicking delete/backspace.
Is there a quick shortcut? Thanks!
Ctrl + D
From Help->Key Assist... there are all kinds of useful keyboard shortcuts for Eclipse.
For Mac users: ⌘ + D
In the future, if you need to quickly find a keyboard shortcut for something simple, just hit Ctrl+Shift+L.
Ctrl + D should delete the line.
You can reassign the Delete Line command to your favourite hotkey.
Window->Preferences
General->Keys.
Now type "Delete" and reassign the filtered command.
if your are using MAC then it is
command + D => ⌘ + D
To quickly find shortcuts, hit Ctrl + L, Ctrl + L (Ctrl+L twice), then type something approximating what your command does in the filter text for the key assignments. This works pretty well for most shortcuts, although it can be a bit tricky for some where the name of their menu assignment bears no relation to that of their command in this list (for instance, Team->Revert to base appears in the keys list as 'Replace with latest from repository'), so sometimes a little lateral thought is required :-) If no shortcut exists, it's easy to add one in the keys dialog.
And if you want it as a list to take a print or something, here is a link to the eclipse shortcut pdf.

press Ctrl+Shift+L TWICE and press TAB then you can type to find your shortkeys
