I am currently working with Eclipse Version: 2020-06 (4.16.0) on a Mac. When I go to Eclipse > Preferences > General > Keys the Undo and Redo shortcut bindings are set to Command Z and Command Shift Z, respectively. However, when I try to undo / redo code that I am writing in PyDev perspective, the shortcuts do not work. Even the Undo/Redo in the Edit field are greyed out and cannot be manually done. Any idea why this is happening and how it can be fixed? Thank you.
This question seems to be duplicated or, at least, here you can find a similar issue.

I used to press Ctrl + 1 in Eclipse (4.3) to access refactorings such as "assign statement to local variable".
Unfortunately this refactoring is not offered anymore. When I press Ctrl + 1, the only proposition I see is "rename in file".
I went in Preferences > Editor to try to find some bad configuration but couldn't find anything.
Did I break something?
edit:
- The file a is Java file, in a Java project, opened in the Java editor.
This is an alternate solution. I'm not sure whether it will solve your problem but you may try using the following configuration:
Window --> Preferences --> Java (select your programming language) --> Editor --> Light bulb for quick assists.
Mark this option as checked & then click on OK.
After doing this, you should be able to see a light bulb on the current line. Clicking on this bulb should give you the same options as you get by Ctrl + 1.
I had the same experience. Eclipse Version: 2019-12 (4.14.0), it is build automatically. I unchecked this in order to speed up eclipse, then I noticed the quick fix only has "rename in this file" left. After I had build automatically back, the quick fix works like a fancy.
I had the exact same problem.
The solution for me was to reinstall some plugins from the Marketplace. The Darkest Dark Theme from DevStyle was the issue. (don't ask me why)
I'm using eclipse on Ubuntu 12.04 and Ctrl+x closes my Eclipse. I tested Ctrl+x in other applications and it cuts text, which is what I want, so it must be an eclipse shortcut binding.
I checked my Preferences>General>Keys settings and couldn't find an exit/quit/explode eclipse command and when I search for Ctrl+x I only see 'Cut' binded to that key combo.
It has been driving me crazy so any help will be appriciated, you go to cut and omg eclipse is closing lol.
I had a similar problem. Here's how to solve it:
When you open Eclipse, go to Window -> Preferences -> General -> Keys.
Search for the 'Cut' command. The Binding option should show 'Ctrl+X'. Change the When option from 'In Dialogs and Windows' to 'Editing Text'.
I checked my Eclipse environment, I don't have this problem. Ctrl+ X is for cut.
I can suggest to go where you did, and look inside the bindings column, if there is any ctrl+x and change it.
Look also for other programs you are running, maybe they listen to shortcuts.
Cheers
I had the exact same problem on Windows 8. The CTRL+x binding closed Eclipse but in the bindings dialog the only binding for CTRL+x was for the cut action. Finally, I have found the solution in the Arch Linux Wiki. See https://wiki.archlinux.org/index.php/eclipse#Ctrl.2BX_closes_Eclipse . It's a bug in Eclipse which can be solved by editing a metadata file by hand.
Previously, using the ALT+COMMAND+R key combination after highlighting a variable name in a Java file would go into the rename refactor mode. Now, the key combination replaces the highlighted text with a registered trademark symbol. How can I get the key combination to go into the rename refactor mode instead of inserting the symbol?
The current file encoding is set to MacRoman, which is the default setting inherited from container. As far as I know, nothing here has changed.
I am using Eclipse Indigo (Build id: 20110615-0604) on Mac OS X 10.7.5. Eclipse IDE for Java EE Developers 1.4.0.20110615-0550 and FreeMarker IDE SDK 1.1.0.v201006011046R-H111-GA are installed. I don't think there are any non-standard plugins.
The only recent change I can remember making is installing PyDev a few weeks ago. With the default PyDev installed, ALT+COMMAND+R opens a context menu in the lower right corner with 2 option: rename and set next symbol (this is in addition to replace the text with the symbol). I disabled the Set Next Symbol key binding in my preferences, restarted eclipse, and tried the key combo again. The text was still replaced by the symbol but the rename refactor mode was not entered did not open. I uninstalled PyDev, restarted eclipse, and tried the key combo again. The text was still replaced by the symbol.
Update (December, 2012): Another user on eclipse forums is having a similar issue: http://www.eclipse.org/forums/index.php?t=rview&goto=990973
Update (January, 2013): I have opened APSTUD-7664 in PyDev's Jira. Hopefully, a developer will pick it up and find a solution.
Same problem here (OS X 10.7.5, Eclipse Juno for Java, build 20120614-1722, PyDev recently installed). The following solution worked for me:
Eclipse > Preferences... > General > Keys
Choose Rename - Refactoring (Category: Refactor - Java)
Click Unbind Command
Click Binding field and type Command-Option-R
Click OK
A possible clue as to what's going on (I don't know): the User column is set to "C" before fixing the binding, and set to "U" afterward.
Ed's unbind/rebind trick didn't work for me, but changing "When" from "In Windows" to the more specific "Editing Java Source" seems to have done the trick.
I guess it's a bit more restrictive, but for my workflow Java is really the only place I'll be doing any refactoring.
If anyone is still having this issue (and it is still an issue with the most recent Eclipse Kepler when you install PyDev), this is the solution that worked for me. It's very similar to Ed's, but I had to unbind on the PyDev command specifically.
Go into Preferences > General > Keys menu:
Filter by the word "refactor" in the filter box. What you'll see is that there's a conflict ("C" in user column):
You need to sort by the highlight the Rename - Refactoring command and sort by binding. Then remove the filter. This will show all conflicts (including the PyDev one that is fouling things up)
Click the PyDev command bound to the same key combination click "Unbind Command"
Now nothing will be bound to that key combination, so just go back up to the correct command, "Rename - Refactoring" and rebind Command-Option-R to it.
When you're finished, it will show as a User defined command (U in user column), but it will work properly in both the project menu and in the code editor. The only thing that won't work is the PyDev command that was bound to it. If you want, feel free to bind that command to an alternative key combination.
I think .. the solution is full resetting. So i do as follow.
My environment is Eclipse kepller and Mac Mountain lion.
Terminate eclipse.
Copy workspace for safety. (Maybe its useless, but for safety...)
Delete .metadata hidden folder from workspace.
Start eclipse, then you see whole new workbench without projects!
Now, import existing project from your workspace folder.
That's all. Your default rename key is restored. And you have refreshed environment.
It's simple.
Have a nice development time.
If I go to Window -> Preferences -> General -> Keys, change the scheme to "Emacs", and click apply, nothing happens.
I'm using Eclipse 3.6.1 on Fedora 14. Is there something I'm missing or is this just broken? Is there a workaround that doesn't involve manually entering all of the shortcuts?
While I don't know about the built in Emacs keys, I do enjoy using Emacs+ for Eclipse: http://www.mulgasoft.com/emacsplus.
The keybindings mechanism in Eclipse occasionally gets confused. Briefly, you have to convince Eclipse to reset the bindings to the default before re-enabling your desired binding scheme. A description of the procedure (that works most of the time) can be found at: http://www.mulgasoft.com/emacsplus/keybinding.
Some users have found that they need to restart Eclipse more frequently than is outlined in the procedure...
Undo is not working for me in ant editor in eclipse.
When I press Ctrl-Z nothing happens.
Is it possible to enable undo somehow or is this a bug?
I am using Eclipse 3.4.2 (Ganymede) on Windows XP Professional.
Yes undo should be working perfectly in an ant editor.
For Ctrl-Z to not workcould mean:
the shortcut has been assigned to another action (Windows > Preferences > General > Keys)
the undo buffer size is somehow at '0' (Windows > Preferences > General > Editors > Text Editor)
a plugin somehow 'steals' the key event for itself
Try a fresh install, and check also with a latest Galileo (3.5RC2) install to see if the problem persist.
Note: zvikico mentions the existence of a known bug with ant editor in 3.4.2
After a quick search, the following bugs might explain your situation:
267780 [ant editor] delete line cannot be undone after cursor has been moved
247434 Failed to undo removal of line in Ant editor, only with 'Eclipse IDE for Java Developers', with Eclipse Classic you don't get this behavior
and finally:
239115 Undo functionality does not work anymore in the ant editor, mainly because a WTP issue, only solved in 3.5
I see this post is very old, but I am adding a response for the people who find this through the search engines.
Ctrl-Z stopped working in eclipse for me when I made a small change in one part of my code which in turn triggered an unexpected infinite loop in a different part of my code.
I used the windows task manager to kill the application that I had been testing when Ctrl-Z had stopped working, and then I used system.out.println() to identify the part of the code where the infinite loop was being triggered.
I then disabled that section of code, which in turn caused Ctrl-Z and everything else to start working again.
I was able to finish debugging from there.
If the CTRL-Z (undo) does not work anymore, you might try that. It worked for me:
go to Preferences -> General -> Keys and click on apply button or restore defaults button
