Eclipse shortcut keys are not working suddenly in Windows [closed]

Asked 24/9, 2013 at 9:47 Answered 18/5, 2015 at 14:26

Eclipse shortcut keys are not working suddenly in Windows. Even basic needed shortcut keys like 'ctrl + F' and 'ctrl + c' don't work. I hope that if eclipse is restarted, it would work, but I cannot restart as my applications are running in eclipse. I ensured that this is happening only in eclipse, not in other applications in my computer.

I'm having this issue. I found that bringing the help up (press F1) solves it. – Gigigigli 20/10, 2016 at 14:24

For me going to another project (same workspace), and CTRL + D worked. Then came back, and noticed it works in the initial project too! – Sunsunbaked 11/12, 2018 at 16:26

I have the same issue in eclipse Version: 2018-09 (4.9.0) - solved it by closing all open sourcecode, opening a java class in a different project and going back to the project i was working in it suddenly was repaired – Hatchett 27/4, 2021 at 13:9

My problem was solved when I restored defaults values of my Keys.
Go to Window -> Preferences -> General -> Keys.
Then, click Restore Defaults button at the bottom, and restart Eclipse.
I am using Eclipse Juno.

I had the same problem with STS(Spring Tool Suite version 3.83) The above solution fixed it. – Rancid 19/1, 2017 at 18:37

I did this and restarted and they were back. – Manatee 9/4, 2018 at 17:16

If some shortcuts work, but others don't, sort the table on the Keys preference page by Binding and check for duplicates. If there aren't duplicates, It could be that your operating system or windowing environment already use them. – Chu 3/12, 2018 at 9:34

I had a similar issue. Turned out that a shortcut of my Radeon Software overwrote the shortcut of eclipse so it wouldn't trigger in eclipse anymore. After rebinding the shortcut in my Radeon Software it also worked again in eclipse. – Sander 2/6, 2023 at 21:37

This is a bug in Eclipse Juno, restarting Eclipse does solve it temporarily, I'll try an dig out the bug report.

Comment from bug description...

I am also facing a lot of problems regarding the keyboard shortcuts. The issue is intermittent and all of a sudden most of the key board shortcuts(specifically f3, ctrl+D, ctrl+O ) stop working unless I restart my IDE.

Facing same issue in Version: Kepler Service Release 2. Build id: 20140224-0627 – Boulanger 6/6, 2014 at 3:35

Restarting Eclipse and even rebooting doesn't help for me; shortcuts still gone. – Illusage 14/6, 2014 at 18:12

I just upgraded to 4.4 Luna and am having this same issue – Cleanse 15/7, 2014 at 16:30

As a developer with multiple workspaces, I just confirmed that this is workspace dependent. My one workspace no longer has keyboard shortcuts, and my other does. Using Eclipse Luna – Cabinda 26/9, 2014 at 15:4

I didn't have backup of the file and I had to undo some code :( – Laevo 4/3, 2015 at 13:27

I just got this problem with Eclipse Luna. Creating a new workspace didn't help, neither restarting whole computer. I'm now in process of copying a fresh copy of Eclipse Luna. – Uropod 20/4, 2015 at 7:39

I had this bug today with Eclipse Mars (Version: Mars.1 Release (4.5.1) Build id: 20150924-1200). Setting the Scheme (Window Menu -> Preferences -> General -> Keys) to "emacs", then back to "Default" and restarting eclipse fixed it for me. – Reservation 24/11, 2015 at 9:12

For me as I installed the latest neon-2 this issue shows up also, fix by goto Window -> Perspective -> Custome Perspective -> shortcuts tab and toggle the checkbox for corresponding shortcuts. – Aixlachapelle 5/1, 2017 at 22:54

Theres a quicker answer for this below instead of restarting eclipse. – Palaeozoology 23/1, 2018 at 2:26

Based on the link posted by david99world

Changing perspective and going back does also solve this, that does looks like is a focus problem.

This fixed the issue for me also - much faster than restarting my IDE every time this bug crops up! – Chiasmus 9/11, 2016 at 14:50

That worked for me when the restarting didn't. – Englis 24/8, 2018 at 9:14

Window > Perspective > Rest Perspective... also works for me. – Excellent 23/11, 2020 at 9:59

My problem was solved this way: Go to Window -> Preferences -> General -> Keys

and look at the "Scheme:" control. Change it to "Default". If only that doesnt do it for you, in the field "Binding:" leave it blank.

For me it worked.

If its already at default, change it to something else, close the dialog, open the keys again and change it to default. Worked fine here! – Operator 13/3, 2017 at 5:28
