My delete key won't work in Eclipse in OS X - eclipse

My delete key isn't working in Eclipse in OS X. However, Shift-Delete deletes.
Delete works elsewhere, so a setting must have been unwittingly changed. Any idea what it is or how to fix it?
Restarting Eclipse didn't help.

Check your key mapping for delete and cut commands:
Maybe the delete key has been re-affected.

I'm on a mac and this is a trip. None of the answers are working for me. I tried everything suggested here :(
I was about to reinstall eclipse and decided to see if a restart would help. I logged off...
 | Log out [user]
and then logged back on and I got control of my arrows and delete key again.
!!! UPDATE !!! If I close one program in the doc I get it all back.
This generally happens to me when Firefox Crashes

I have this problem with Helios too sometimes. It seems like it has to do with changing focus to another app and when i return, the arrow keys and delete don't work. If you also have problems with the arrow keys, the solution is to change the
Preferences | General | Keys | Scheme
I just change it to something and change it back and it solves the issue.

STRANGE SOLUTION WORKS! Recover by randomly closing one program in the Mac dock
Pick any program in the dock and close it. This usually happens to me when Firefox crashes, but it might work for you as well.
Added this as an alternative answer because it appears to be relevant —Shanimal

None of these answers help me. It works after following actions:
Go to Preference > General > Keys > Delete
Clear Binding text field
Assign Tab to Binding text field, then click OK (it works as press tab to delete files)
Go back Preference > General > Keys > Delete
Clear Binding text field
Assign "Delete" to Binding text field, then click OK
That's all.

This was a known bug in previous (non-Helios -- 3.6) versions of Eclipse. Apparently, the bug was addressed in Helios:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=283415

Hi Fn key and delete works for me.
What I did I clear the binding and Apply
Then I again set the binding and Apply.
Then Restart the Eclipse.

I just had the same problem too. Got the delete key to work again by right clicking one of the tabs I had open in eclipse and clicking "Close All"
Somehow that worked.
Someone mentioned it generally happens after firefox crashes, oddly enough that did happen after my firefox crashed.
Hope this helps someone.

The same problem here using Mac OSX 10.7.5 and Eclipse 4.2.2
loosing DEL Key, Save Shortcut (and maybe others)
Solution for me is to click into another file-editor window and back into the one i was editing.

VSCode some shortcuts not working properly

latest version 1.40.1 on Windows 7 x64. I am developing in Java.
The most common shortcut, "go to definition" F12 and "auto fix" ctrl+dot
I tested it on another computer with 1.40.1. It works properly.
I have follow the key binding troubleshooting guide. When I record my key ctrl+dot.
It shows ctrl+oem_period. Looks like the OS is sending the correct keys to VSCode.
I couldn't find a way to reset VSCode key bindings and do not know what is actually causing this.
What should I do next? Completely reinstall everything is the last resort.
With the command Developer: Toggle Keyboard Shortcuts Troubleshooting, you can see which command is linked to a shortcut. It could happen that an extension is overriding the expected behaviour.
For example, I had an extension overriding the shortcut to reopen a closed tab, which didn't work anymore.
This resolves my issue:
Change your "keyboard.dispatch" to keyCode in the file settings.json
{
"keyboard.dispatch": "keyCode"
}
Your operating system keyboard shortcut is overriding the vscode shortcut. You should check your operating system shortcut key instead.
Just restarted the Visual Studio Code and the keys are working fine.
I was facing the same problem after I updated my Intel Graphics Command Center using Windows Updates.
The Add One Cursor Above/Below shortcuts were not working for me.
I started the Intel Graphics Command Center, and then went to System > Hotkeys tab, Enabled System Hotkeys as shown in the picture below.
I flipped my screen a couple of times using the keyboard shortcuts and then disabled once again.
Then switched back to VSCode and the keyboard shortcuts were working!!
In my case, "cmd+k cmd+0" which helps to fold all regions was not working.
Another extension was using the same shortcut. I followed the steps below to fix it.
Here are the steps to fix this
Press "cmd+shift+p" to open command palette
Type "Preferences: Open Keyboard Shortcuts" and hit enter
Press "option+cmd+k" to start recording keys.
Press the short cut keys that are not working (in my case "cmd+k cmd+0" ). This will list all the instances of that shortcut keys. And there are probably multiple instances of the same keybindings with some of them being used by an "Extension" as shown under the "Source" column.
Remove that and keep only that instance which says "Default" under "Source" column.
Now, you should able to use the default keyboard shortcuts.
Resolved :
Facing similar issue. Several keyboard shortcuts stop working when code starts running.
In my case it was happening because of notepad++ extension. Disabling that extension resolves the issue.
Sometimes this can happen because of change in environment variables. Please check if any recent program installations has made that change
You may also need to check the when clause of the Keybinding. In my case, I was struggling with why "Command+R" wasn't reloading the window on my Mac. By right-clicking on the row of the relevant command in Keyboard Shortcuts, then clicking "Change When Expression" and removing the expression completely, the keybinding now works as expected.

Try turning on Num Lock, it worked for me.
Extensions you add to VSCode also can override the ordinary behavior of shortcuts. I faced to this problem, I've noticed that the ordinary shortcut command + L which selects the whole line, does not work, and the reason was Live Server extension, which overrides that shortcut, after its deletion shortcut became work properly
I have tried many methods to solve this problem ,not every problem of mine got solved so I use this method after I cant find the solution.
you can first uninstall the VS code and then delete the .vscode file from C=>user=>admin=>.vscode
after that reinstall vscode ,from my end its working fine after doing this.
My issue is niche but never know, might help someone - YouTube Music Desktop player app was hijacking cmd, shift + l for me.
In my case, my Ctrl keys were mapped to the Toggle extension and this extension could not overwrite one of my settings in the settings.json because I had pending changes that hadn't been saved. Once I saved the file, I was able to use the toggle keyboard binding again. I used the guidance from Martin above to determine the cause of the issue.
99% works.
Forget everything that may overrides your keyboard shortcuts. The problems is your keybindings.json file, if you fix it you'll fix your problem.
I found the solution and I've explained it in the following link:
Why vscode shortcuts don't work properly?
Woo, found my issue was Razor Naga stuff. After I updated some of the Razor apps (it has Synapse, Cortex, etc), this issue started happening. Now, I saw these apps are running in the background although I am not using the devices at this time, and once I quit them, VSCode went back to normal thankfully.
In my case, I have installed some "vim keyboard extensions" and others. so I have uninstalled all the extensions related to the "keyboard" i.e. "vim keyboard extension" and now it is working fine. it is recommended to check if you have downloaded any extensions for the "keyboard" in the extensions and uninstall it. It might solve the issue.
This worked for me to fix CTRL+Space "Trigger Suggest". First I found and disabled this setting in: System Preferences > Keyboard > Shortcuts > Input Sources
Then I followed #ryandidevar's instructions and replaced everything for Mac: https://stackoverflow.com/a/72187880/14353462
Finally, I set "Trigger Suggest" in VSCode > Preferences > Keyboard Shortcuts to: CTRL+§ (which is right next to my "Z" key). CTRL+Space just would not be accepted under any circumstance. Now hitting CTRL+§ finally brings up the suggestions!
MacOS users,
This is a default macOS shortcut. VSCode is never getting the meta+shift+L message from your OS. Your OS is hijacking it. You need to disable it.

I just deleted folder in %APPDATA%\Code\ resets whole vs code and fixed my problem with alt + b and other vs code shorcuts not working
For me, It is the keyboard layout setting that causes this. Use English US keyboard setting.

Eclipse IDE Redo and Inspect key command Conflicts

This is really irritating me , Am using Eclipse IDE(JUNO) In Apple MacBook Pro Mountain Lion for my project development,
whenever i press Cmd + Shift + z instead of redo action , i am getting an popup in bottom right corner like below,
i even tried to change the key comands in Eclipse => Preferences => General => Keys , but nothing is working, always getting this popup.
Does anyone have any solution for this?
I've been suffering with this issue too and just found the solution:
With Eclipse not running, edit org.eclipse.e4.workbench/workbench.xmi and search for 'COMMAND+SHIFT+Z'. You'll find two <bindings> instances - one pertains to Redo and one to Inspect. You'll need to do a search on the command="xxxx" attribute to do a lookup to see which one belongs to the <commands> with elementId="org.eclipse.ui.edit.redo" and which one belongs to the one with elementId="org.eclipse.php.debug.ui.commands.Inspect".
Once you've determined which <bindings> is for Inspect, change its keySequence to something other than 'COMMAND+SHIFT+Z' to remove the conflict.
:-)
I had a similar issue with shortcuts. Have you restarted Eclipse after updating the key bindings be to non-conflicting? That was needed for me, but after that, it was consistently working.

Validate Autocomplete in Eclipse

Coming from Visual Studio and starting a project in Java, I realized I couldn't cope with having to press ctrl+space to have the autocomplete panel show up. An easy workaround was to set all keyboard characters to be trigger characters for autocompletion.
My only problem is that, when presented with autocomplete suggestions, a single press on the space bar will write the first proposition. In situations where I'm happy with the suggestions, that's just fine. In situations where I actually want to use what I wrote down initially, I have to press 'escape' first to remove the autocomplete panel before I can press 'space' safely.
Netbeans doesn't use the space bar as a validating key for autocompletion (only 'enter' does that) and I like that behavior. Any way to replicate it in Eclipse?
Thanks in advance for your answers!
EDIT: I should have mentioned I'm using Eclipse on the Mac.
Guillaume
I have the same problem with Eclipse Indigo on Windows XP actually. Coming from intellij idea, I also felt the need to set the whole keyboard to trigger auto-complete.
A quick proof that SPACE key does accept suggestions : type inte on a new line. If the auto-complete menu shows, press SPACE. It goes for Integer.
If anyone knows how to set the SPACE key to "ignore suggestions", it would be great, because the escape key on my keyboard is also too far away :)
Thanks
Edit : actually the best would be to have only the ENTER key validating, because ';' and '(' also seem to validate
I just tried to reproduce your behavior, but couldn't. Here is the configuration I have (and the steps I have done to reproduce):
I have installed Indigo (current version of Eclipse, version number 3.7).
I did not change any configuration there, this is what is the default:
Under Window > Preferences > Java > Editor > Content Assist, I have the following settings:
Completion inserts (instead of overwrite)
Insert single proposal automatically (which is ok most of the time)
not insert common prefix automatically
I have a simple class, go down to a method, and do the following steps:
Enter this.no and wait some time. Sometimes I have to press CTRL + SPACE, sometimes not.
Proposal pops up which includes notify and notifyAll.
I press SPACE and a space is inserted in the text, the autocomplete suggestions are closed without inserting anything.
I do not know if older versions of eclipse have the same behavior.

Really weird eclipse keyboard behavior/bug?

I am using Helios on Mac Snow Leopard. I don't know why but all of a sudden my arrow keys and delete button start not working only on Eclipse (so Eclipse ignores them) but the rest of the buttons works just fine. There is no exception/error thrown anywhere on the screen. I don't exactly know how to reproduce this malfunctioning.
All I can say, I am having exactly the same problem with this guy down here. Bad thing about it, the post sent in year 2002:s
Is there any one of you having the same issue? Any suggestions?
Edit:
Please mark "me too" on this bug report hoping that it will be fixed soon.
I was able to "restore" arrow and backspace keys by "Refreshing" the project.
UPDATE: 7/11/2017 I've not had this problem reoccur in a couple of years now. Either Eclipse fixed the problems or a more recent version of Mac OSX has fixed something. For the record I'm running Eclipse 4.5.2 on OSX 10.11.6.
UPDATE: 4/29/2011 Now it looks like this is not a Workspace or keyboard preferences issue at all. This just happened again but restoring from older Workspaces did not fix the issue. I finally had to reboot my Mac which seemed to resolve things. I'm going to try a restart in the future immediately if I see this again. I've submitted this bug with Eclipse. Please add a "me too" comment to the bug if it has not been fixed and you can reproduce this on your system.
I also have heard that on Macs, you can solve this by getting the unit to sleep either by closing the laptop lid or pulling the Apple menu down to sleep, wait a few seconds, and then starting it again. I've not tried this yet.
BTW, when this happens refreshing and other mechanisms have not worked.
UPDATE: 4/13/2011 Although the below instructions did fix my keyboard issues, I discovered other problems with my configuration and was finally forced to recover my Workspace from backups.
NOTE: This is not recommended but is here for information purposes. Typically these keys are handled by the native widget and are not defined.
So I just had the same problem under Eclipse 3.6.2.r362 on Mac OSX 10.6.7. Delete to the left and arrows not working. They worked in other applications. Option-Arrows worked fine to move a selection around. Arrows worked in the keyboard preferences window. Switching to another application and back didn't work. Restarting eclipse made no difference. Switching keyboard schemes from Emacs -> Default -> Emacs didn't work. Pressing all of the modifier keys did nothing. I tried all of the following and nothing works: Rebuilding the project, refreshing the source, restarting Eclipse.
Finally, I was able to fix this by going to the Preferences -> General -> Keys and resetting each of the bindings for the following keys. The bindings for each of the keys were blank.
Delete Previous to backspace
Line Up to up arrow
Line Down to down arrow
Previous Column to left arrow
Next Column to right arrow
This worked but then I noticed that all of the emacs key bindings were screwed. I thought they worked before so I'm not sure when this happened. I had to restore default key bindings (after writing down the ones that I had customized) and then restore my customized settings.
Makes me wonder what other key bindings have been reset and what did it. Frustrating but at least I can get back to coding.
If you see the same symptoms on Eclipse Windows, just press all your mouse buttons (including the wheel if you have one) at the same time together, and that seems to fix it.
Same weird problem, this worked for me: I just figured out that if I switch editor and then back again, backspace starts working again. (source)
For me, the root cause was my mouse.
Backspace and navigation keys did not work. I could fix this temporarily by manually setting the key bindings as described on this page.
The root cause and permanent solution was fixing the stuck 3rd mouse button on my Evoluent Vertical Grip mouse. Since I never used that button, I didn't notice that it was permanently engaged, probably from the mouse sliding off the desk on to the ground one too many times. Once I was able to get the button unstuck, the problem was solved immediately.
This was really frustrating. I spent weeks wondering why it was happening and sporadically searching the web for answers. Of course I had a temporary solution, but the fact that it kept happening was annoying. I tried reinstalling Eclipse from scratch, trying different versions and switching workspaces, but nothing worked. I'm surprised it ended up being a stuck mouse button after all that.
Also check that someone has not installed the vrapper plugin so that Eclipse accepts vi/vim like commands. If this is the case pressing i allows you access the editor window. If you are unaware that a work college has installed it (glares at someone) it can be a right $%#&$#! If installed there will be a V icon in the top toolbar. This plugin can be removed by going to the directory where Eclipse is installed in a term window and running
find . -name '\*vrapper\*' -exec rm -rf {} \;
It is that or tax you brain but supposedly increase your productively by learning all the Vim commands. Hope this helps someone...
In Windows and Linux environments I have experienced such issues when the system believes a modifier key is pressed. By pressing and releasing all modifier keys the issues often perish. However, on OSX I did not experience such issues, so this might be entirely wrong.
If the simple idea does not solve the issue, you could try to start a new workspace to see whether some preference causes the issue; or you could download a new Helios instance to check whether its working. I know, these are all serious issues, but may locate the problem.
Otherwise, you shall take a look at the question asked not long ago about keyboard issues, maybe there is some hint how to solve it.
I had the same problem with the "Delete" key in Eclipse 3.7.0 on Windows Vista. Suddenly the key stopped working and I couldn't figure out why. Recently I found a way to fix it when the problem occurs - it works for me every time:
In a code editor window in Eclipse, hoover on some method or variable or what have you, until the popup window appears with "Press 'F2' for focus" in the lower right corner. Click the popup window to switch focus, then click the editor window again so the pop-up disappears, and voilà, the Delete key works again.
Had this same issue. Turned out to be my middle button on my wireless mouse being pushed in my laptop bag. Normally I turn my mouse off, but this time I forgot. Glad that other people had this problem, otherwise I'd still be looking for the cause.
I have encountered this problem for years. It happens so infrequently however, that I almost always forget what I did to solve it. Restarting fixes it most of the time i think, and a few times "refreshing" worked, but nothing works 100% of the time.
In any case, someone on the bug report suggested just putting MacBook in Sleep cycle. This worked like a charm for me, so putting it out there for future reference.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=344290#c24
Incidentally, I have experienced similar behavior with other applications, in particular Firefox. My thought is that it has to do with key bindings in general, and any application that provides overrides for defaults in the OS (this is a pretty huge assumption, so take with a correspondingly large grain of salt). I have also had this happen to me in Xcode, but a simple restart of the application fixes, whereas with Eclipse that wasn't sufficient most of the time.
Using eclipse JUNO on Win XP I also experience this issue.
Restarting the workbench using File > Restart does not work, but closing eclipse and starting again with -clean at the command prompt the keys start functioning again, without restart windows.
Note - Just found this fix elsewhere - you can fix this on Mac OSX by force-killing finder. That worked for me perfectly. Didn't need to restart!
For some odd reason, opening the preferences window and closing it right away, solves this problem for me (other solutions here didn't work).
Just in case this helps someone... I accidentally got things working again by doing the following:
Opened the offending file from the command line (I used 'vi').
Made the edit I wanted to make and saved the file.
Went back into Eclipse to refresh and redeploy my app.
As soon as the editor (this was a JSP file, btw) refreshed, I once again had full use of arrow, delete, etc.
YMMV

MacBook Pro 10.6.8, Eclipse Helios all of a sudden delete and arrows no longer work. Reboot worked for me.
I am also facing the same problem. In my case only the delete key is not working. I am using eclipse helios in ubuntu. The solutions given here are not working. However, restarting solves the issue.
I have the suspicion that this happens after updating Java on my Mac. So after updating Java it seems to be a good idea to reboot the machine always.
I got this same problem when I started using JRobot. In one piece of code I pressed the mouse but did not release. By releasing the mouse in a later piece of code I managed to solve the issue. You can recreate this problem using the code below. Release the mouse button to solve the issue.
Robot robot;
try {
robot = new Robot();
robot.mousePress(InputEvent.BUTTON2_MASK);
//robot.mouseRelease(InputEvent.BUTTON2_MASK);
} catch (AWTException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
Pressing left and right mouse buttons simultaneosly multiple times worked for me.
Using eclipse Luna (4.4) on Redhat and viewing via Xming (Windows 7, 64-bit), I could not use backspace, arrows, delete or even enter, but alphanumeric worked. This problem was not intermittent, but always there from the start. For me, I found that setting a break-point in the code, running and allowing eclipse to switch perspectives fixed it every time. Hope it helps someone else as the above suggestions (ie switching editors, changing key mappings, refreshing and restarting eclipse) did not work for me.
One interesting diagnostic of the problem I had was that going to the screen where you change the key-mappings, I was able to use the delete key. But not in java files or untitled text files.
WORKED!!!
I'm using Eclipse Luna and Windows 7, but guess it works in all kinds as well.
In Eclipse, go to tab Window->preferences->General->keys
Then, find the Command "Delete" and "Delete Previous" in the list, and check if
they are assign with something or not. If it is assign with the wrong key, click in "Unbind Command".
Just select the command that you want to change and press the key that you want to be on the "binding" field.
I think it works for Next, Next Column, Previous, Previous Column, Line Up, Line Down, or whatelse you want!!
Had, similar problem with not working “enter” and “delete”, none of above methods helped me – to fix problem I had to switch to default java formatter (one I was using somehow stopped working)
For me it was that the keyboard layout accidentally changed to vietnamese language and there are inherent key mapping combinations that create trouble when editing.

Eclipse (3.4): how to get Problems to appear automatically if one has errors?

When I build my projects in FlexBuilder, I want to see any errors immediately; I don't want to have to hover or open the Problem pane every time, nor do I want to always leave it open.
Any ideas?
I do not think this is a problem.
As far as I know the Eclipse settings and there is no such.
You can use shortcut keys SHIFT+ALT+Q and press X to fast open the problem panel.
