Build Identifier: 20110218-0911 Two times now I've been working in eclipse and also switching back and forth with other applications when the arrow keys and the left-delete key stops working in the Java editing windows. Inserting letters and the like seem to work fine and the right-delete works but not left-delete (sort of important) or the arrow keys. The keys work in other applications without problems. When I look at the keyboard preferences I see that the preferences for those keys has magically been disturbed. This has now happened to me twice. Restarting eclipse does not fix it. Last time I was able to fix it by restoring my workspace directory from backups but this time even that doesn't work. Maybe I need to go to a backup further back. I see a lot of similar bugs in the list but none that seem to match mine or that are recent. Apologies if a dup. I see others complaining about this: http://stackoverflow.com/questions/5263921/really-weird-eclipse-keyboard-problem-bug/5585512 Reproducible: Couldn't Reproduce
So now this does not look like a Workspace issue at all. Although restarting eclipse did nothing, rebooting my Macintosh seemed to fix the problem -- even with the old Workspace. No idea why the keys worked in other applications fine (I did not try another Java application) but Eclipse needed the reboot. Hopefully this will happen again so I can try a reboot immediately to see if it fixes the issue.
Also, I see that the keyboard preferences may _not_ have been changed because older Workspace backups did not work as well and the 'Delete Previous', 'Line Up', 'Line Down', 'Previous Column', and 'Next Column' commands are all not mapped in my current working configuration. The default must be to do the right thing with those.
2 things that could help diagnose this: 1) Could you attach a log file? It would be in <workspace>/.metadata/.log 2) If it's partially repeatable (it occurs after you've been working for a while) you could run with http://wiki.eclipse.org/Platform_Command_Framework#Tracing_Option If you could find a specific case that stopped working, like CTRL+Right (or CMD+Right) I can track down the command Id (in my example, it's next word). That would help narrow down the tracing. The tracing would indicate when some part of the system is changing/resetting the keybindings. I'll just mention that in the text editors and java editor, the standard arrow keys (up, down,left, right) are not part of the keybinding system. There is a LineUp command that can be bound (to provide an emacs binding, for example). If it is just a keybinding problem, a hack workaround without having to restore your entire workspace is to delete the org.eclipse.ui.commands pref from <workspace>/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.ui.workbench.prefs while your eclipse is not running.

(In reply to comment #1) > Hopefully this will happen again so I can try a reboot immediately to see if it > fixes the issue. That is consistent with my knowledge that the arrow keys are just left to the native widgets. Please let us know how it works out (it might still be SWT interacting with the native Mac widgets). PW
Created attachment 194378 [details] Workspaces/currentBranch/.metadata/.log file
Comment on attachment 194378 [details] Workspaces/currentBranch/.metadata/.log file Last 2 days of the log. Problem happened on 4/29/2011 between 10-11 localtime.
Thanks much for the feedback Paul. I've attached the last couple days of my .log file. If it happens again, I'll run with the debugging and post the results. Thanks also for your work with Eclipse.
Created attachment 200940 [details] Debug log showing [BS] commands that don't do anything. Finally got this to reoccur. You see: WorkbenchKeyboard.press(potentialKeyStrokes = [BS]) but nothing is deleted from the document. The ARROW_LEFT are also ignored. The CTRL+B works and do does the DEL.
This problem just started happening to me as well. Version: 3.6.2 Build id: M20110210-1200 Platform: Mac OS X Keys affected: Delete and all 4 arrow keys Resolution: Reboot Initiating event: Unknown. Keys stopped responding in the middle of coding (Eclipse had been open for several hours). Failed attempts to fix: 1. Restarted Eclipse 2. Checked for alternate key bindings in preferences. Only correct binding to delete found. I first noticed this within the last week.
Ditto here I just had the same problem using Eclipse Indigo: Version: Indigo Service Release 1 Build id: 20110916-0149 I found out about this bug from the Stackoverflow thread: http://stackoverflow.com/questions/5263921/really-weird-eclipse-keyboard-problem-bug So far I haven't rebooted, I've tried to set the bindings manually as explained in the Stackoverflow thread and it worked, I've recovered use of the missing keys (backspace & arrows)
Just had the same issue. Additionally, Up and Down arrow keys are also not working. Nor is the Delete button.
I'm having this problem, too. Version: 3.7.1 Build id: 20110916-0149 Platform: Mac OS X Keys affected: Delete Left and all 4 arrow keys Resolution: Reboot Initiating event: Unknown, but happened when switching between views. Restarting Eclipse didn't fix it. The key bindings for Line Up, Line Down, Previous Column, Next Column and Delete Previous vanished.
Version: 2.8.1.RELEASE Build Id: 201111221000 Platform: Mac OS X 10.7.2 Keys affected: Delete Left and all 4 arrow keys Resolution: Add bindings back Me too. Found out about it at the SO thread: http://stackoverflow.com/questions/5263921/really-weird-eclipse-keyboard-problem-bug.
I have exactly the same bug as the one in 'Description'. I use Indigo on Mac OS X Lion. Eclipse version info: Version: Indigo Service Release 1 Build id: 20110916-0149
Hello, It seems that I had the same problem. But I'm on a DELL Latitude D630 with Win XP... In fact, it seems I have some problems with my mouse too : When clicking on the editor part of the file, I can't no more click away in Eclipse, the editor is acting just like it is alone : if I click on a menu (top of the editor), it's like I clicked on som text I don't see but upper in the editor, just like a great transparent window containing the editor was over all other things in Eclipse. I have to switch app (Alt-Tab) and come back to be able to use my mouse again on menus and treeviex of my project... Do I have to open a new bug ? thx
In fact, I just wanted to add the build version : Version: Indigo Service Release 1 Build id: 20110916-0149 But... After selecting text of the "About Eclipse" window, I can't click on the "OK" button... Just like with the editor... Am I doing something wrong ?
I'm experiencing this problem too. I'm on Version: Indigo Service Release 1 Build id: 20110916-0149 OS X 10.7.3 External Keyboard, External Bluetooth Mouse If I switch out of Eclipse and back into it they work for a while.
For me the settings for `Preferences -> General -> Keys` - Delete Previous - Line Up - Line Down - Previous Column - Next Column - Select Next Column - Select Previous Column had to be reset. Works for now
Same issue for me: Mac OSX Lion Build id: 20110916-0149 Happened to me twice in the last couple of weeks. I also don't know what started the issue and can confirm that only a reboot resolves the issue. Restarting eclipse doesn't help. I'm working a lot with eclipse, but it happens rarely. So I've no idea how to reproduce unfortunately.
I just experienced this for the first time today, delete (backspace) and arrow keys stopped working in the editor window. All other keys are functional and the aforementioned keys work in other applications. Restarting eclipse did not resolve the issue. I have not set any keybindings, nor rebooted my machine (yet). I was directed here from the stackoverflow post as well. http://stackoverflow.com/questions/5263921/really-weird-eclipse-keyboard-behavior-bug I'm using: Eclipse 3.6.2 Mac OSX 10.6.8

All I'd done was exit and re-launch eclipse multiple times with no success, I'm not sure what caused it to work this time but will update this again if I figure anything out.
I'm seeing a similar problem. Suddenly all my arrow keys and left-delete key stopped working in Eclipse. Pressing Cmd+Left or Cmd+Right for navigation does work. I've tried starting a new workspace and edit a normal text file. Same problem. Restarting both Eclipse and the computer does not help. Using Eclipse SDK Version: 4.2.0 Build id: I20120503-1800
Some additional information. I decided to following the instructions in the Stack Overflow link and found that "Restore Defaults" will in fact clear several key bindings including "Delete Previous" and "Line Up".
This issue has repeatedly crept up on me the past few days so it has been quite annoying. However I discovered that the situation can be resolved by putting my MBP in a sleep cycle.
I have also got the same bug. My arrow keys are working though. I have found only the delete key not to be working.
Exact same issue on Lion + Juno.
what a pain, just ran into this and took me a while to figure what was happening.. could someone attach a working keybindings file.. it has happened to me 2x and i would rather just replace the file and restart eclipse.. or has anyone tried the procedure mentioned in comment #3?
Similar issues here with Eclipse 4.2 on 10.6.8. Resetting the key bindings to default values did not resolve the issue, but manually adding key bindings for the cursor keys seems to have done the trick. However, now I can't use the cursor keys to select quick fixes any more - the cursor keys move the cursor around instead of selecting an element from the list of quick fixes.

Your second observation is probably related to bug 382839 PW
Same issue, Eclipse Build id: 20120216-1857 on Win 7 x64
I have the same issue on Linux (Lubuntu 12.10).
Me too: working in Eclipse 3.8.0 on Ubuntu 12.10, build id:I20120502-2000. Restarting eclipse did not solve the issue. Restarting my machine did resolve the issue.
Me too, working with: Windows XP SP3 (32 bits) Version: Juno Release Build id: 20120606-2254 Additionaly other bindings such us Ctrl+F, also stop working. Restarting Eclipse brings the mappings back for some time.
I am also affected: Version: Juno Service Release 2 Build id: 20130225-0426 Ubuntu 12.10
Seeing this in Ubuntu 12.04, Eclipse 4.2 build 20130225-0426 Specifically lost the delete key, then later ctrl-c/ctrl-v.
also happens on linux eclipse juno - whenever edit session detects project errors shown in red this condition then disabled my Delete key from working
I suspect this is the same as bug 413977.
> I suspect this is the same as bug 413977. Probably some of the later comments are, but the original bug was on 3.x (where bug 413977 doesn't occur). And the original bug couldn't easily be resolved by switching focus (not even restarting Eclipse seemed to be enough).
Version: Kepler Service Release 1 Build id: 20130919-0819 Platform: Ubuntu desktop 11.11 (I think) Keys affected: Backspace and all 4 arrow keys Resolution: Restart eclipse - works for a few mins. Leave to stand for 15 mins also fixes it. Oddly, leaving Eclipse sat for a time period while I field a phone call, lookup my eclipse.org password and find this bug, it has now started working again when I went back to it. I think that was about 10-15 mins, so not an workable solution.
I experienced the same problem with Eclipse Luna on Kubuntu 12.04. Version: Eclipse Luna (4.4.0) Build-id: 20140612-0600 Platform: Kubuntu 12.04 Resolution: Restart Eclipse Steps to reproduce: Unknown
I have just hit the same thing with the latest Luna service release. Resolved by reloading. Version: Luna Service Release 1 (4.4.1) Build id: 20140925-1800 Linux 3.10.0-123.9.3.el7.x86_64 Red Hat Enterprise Linux Server release 7.0 (Maipo) fully updated with the Gnome desktop.
Happens to me on Kubuntu 14.10.1. Seems my key binding got messed and a lot of default ones like delete previous are unassigned. When trying to assign de delete key to it, the following error appears: Error notifying a preference change listener. Check the log for details. loader constraint violation: when resolving interface method "org.eclipse.e4.ui.bindings.EBindingService.getPerfectMatch(Lorg/eclipse/jface/bindings/TriggerSequence;)Lorg/eclipse/jface/bindings/Binding;" the class loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) of the current class, org/eclipse/ui/internal/keys/BindingService, and the class loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) for resolved class, org/eclipse/e4/ui/bindings/EBindingService, have different Class objects for the type eclipse/jface/bindings/TriggerSequence;)Lorg/eclipse/jface/bindings/Binding; used in the signature

I started to notice that I "loose" the delete key on openSUSE 13.2 with Eclipse Mars (4.5) M6 since I switched over to Eclipse Mars. I have recognized, that I frequently loose the key's function after I pressed Ctrl-F and doing some searches.
Please note that this bug report is against Mac. All recent comments are towards Linux, and those are probably duplicates of bug 435742.
You sure this is Mac specific? Now it started hitting me too, on a regular Linux system with MARS.2. On another, it works just fine. Even this one worked fine for days. Now, suddenly happens all the way again. I feel that it starts quickly after using the CDT debugger but not sure. Anyhow, most Ctrl-* combos are failing (including popular like Ctrl-Backspace), Del and Ins buttons are failing. This happened three times in a row now. Restart Eclipse, work a couple of mins, and keyboard input is fsked. All other windows around are working fine. Window manager is IceWM, normal X11 from Debian Sid, pure Desktop environment on native hardware.
Doubt it's Mac specific, I'm seeing failures like this using Neon on a bog-standard Windows 7 system. Special keys will stop working.
