Shortcut Control + Enter stopped working

Question

All of a sudden, Control+Enter stopped working. I need to use Control+Alt+Enter. 
 I see that this question has been asked before but didn't get any answers. 
 Any idea?

Have you looked in the keyboard shortcuts section of Options to see whether it's still shown there? No reason why it would suddenly disappear from there, but still...

 In the absence of you responding I wonder if you just selected the "Trados" profile as opposed to the "SDLX" or "Default"? I know you said "all of a sudden" but maybe you changed the profile? Differences are these. 
 Trados profile 
 
 SDLX Profile 
 
 Default Profile 
 
 The only difference is the very keyboard shortcut you are using. You can check under File -> Setup -> Manage User Profiles

Trados Studio > 1. Trados Studio
