Go to file shortcut Ctrl + Alt + Minus issue in jdeveloper

I faced all of a sudden Go to file short cut in JDev IDE stop working. To resolve this, I followed below mentioned steps. 

Step1: Close the Jdeveloper IDE.

Step2: Go to your jdeveloper system folder and find for the folder 

'o.jdeveloper' and edit  ide.properties file.

If you observe,  Below mentioned values were set to zero. So, to fix the issue, we need to restore 

 default values.

ide.goto.file.width=400

ide.goto.file.height=300

ide.goto.file.x=440

ide.goto.file.y=234

save the file and restart your JDeveloper. 

Hope this Helps!.
