# TIL: ctrl + space: Eclipse Content Assist on macOS

When I tried to use `ctrl + space`, it brings out the Input Sources while `cmd + space` brings out Spotlight. How to use this shortcut for content assist?

Go to System Preferences -> Keyboard -> Shortcuts -> Input Sources

* Deselect the check box labeled: \`Select the previous input source.\` It is also using the ctrl+space key combination.

Go back to Eclipse, and try content assist again.
