We all know that we can use Ctrl + Shift + R to search any file in the workspace. But today, I surprisingly found out that it is not working anymore.
Ctrl + Shift + H and Ctrl + Shift + T are working though.
I believe I am missing a setting somewhere possibly in Window -> Customise Perspective menu. Not sure what is it exactly.
Any help is appreciated.
Just realized this morning that I have a screen capture tool called Snagit installed which uses the same key combination to start capture.
When I closed Snagit, Ctrl + Shift + R is back in action in Eclipse.
But not sure why the same Ctrl + Shift + R did not even open Snagit last week when I tied so hard. May be Snagit was not running last week!
I had the same problem in Eclipse. And it occured when I reopened my Workspace. In my case, when I re-started eclipse, the workspace opened in J2EE perspective by default. Ctrl+Shift+R does not work in this perspective. I changed my perspective to 'Java' and it started working again.
Maybe you have the same issue.
A window manager application 4tray Minimizer interferes with Ctrl + Shift + R by default.
Do you have any AddOns installed? check if any of these overrites the Key combination and change it if though. If this doesnt help then check the Eclipse settings.
If it is Mac then you may have to use CMD + Shift + R.
Maybe other plug-in also defines that key binding. Use Ctrl + Shift + L to list all available shortcuts on the current context to check the whether someone conflicts with the JDT's.
I also faced the same issue and managed to resolve it by following steps:
Open or search Snagit 9.
Click Tools > Program Preferences
Un-check or remove check boxes under 'Repeat last capture hotkey' and click OK.
If the conflict is with Snagit setting global hotkey, then change this in Snagit.
Tools>Program Preferences> Hotkeys and change default key combination to something else that doesn't conflict (e.g. just check Alt)
Or try change hotkey on layout switch, I my case after using Windows many year I set it for Alt + Shift and it's why I can't use Alt + SHIFT + R in Eclipse. When I'm turning to Caps Lock all works fine.
If the problem is not with your key combination, there is another issue which will bring up the Open Resources view but will not display any results when you type the resource name you are looking for. This happens especially when your projects are organized into eclipse working sets.
Bring up the open Resources view with your key combination or using the menu bar. On the right-hand-side just below the close view icon (x) there is a small icon with a triangle. Click this icon and then click on "select working set". This will bring up the "select working set" view. In this view select the "Windows Working Sets". Then select OK.
