Ctrl + Space not working for content assist on eclipse

Question

My problem is that the content assist window won\'t pop up after clicking Ctrl + Space. I checked my shortcuts and the content assist is bound to Ctrl + S

Answer 1

For that Go to

Eclipse --> Windows --> Preferences --> Java --> Editor --> Content Assist --> Advanced --> select all Java & Java Type Proposals.

and check mark : Java Proposals(Code Recommenders)

Answer 2

Go to Windows > Preferences > Java > Editor > Content Assist > Advanced > select all Java only. If you select all, then multiple occurrence of same instance would be shown in Suggestion list. which might be annoying some times.

Answer 3

Though I have eclipse proposal settings configured properly it was not working for me. In my case Ctrl+space key combination was hijacked by another background running process (I was running AllwaysOnTop utility for windows). it worked after exit that process. :)

Answer 4

In my case; Window>Preferences>Java>Editor>Content Assist>Advanced

Make sure Select the proposal>Template Proposals,SWT Template Proposals,Java Proposals ,Content assist cycling>Template Proposals,SWT Template Proposals,Java Proposals is ticked.
