Eclipse shortcut keys are not working suddenly in Windows, Even basic needed shortcut keys also like 'ctrl + F' or 'crtl + c'. I hope if i restart the eclipse it will resolve, but i can not do, bucause my applications are running in eclipse. I ensured that this happening in eclipse or all windows. But not happening same in notepad++ editor.
It looks wonder but it happening.
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.
