ADT short-key Ctrl+Space doesn’t work on Windows 7

In a customer workshop I came across an issue when trying to show the Content Assist (Ctrl+Space).

It did not work and I noticed that the language settings were Chinese.

My first thought was that this was just a wrong setting so we switched the language settings to German.

But as soon as I tried to show the Content Assist it turned out that the Content Assist still did not work and that the language settings were back to Chinese.

Searching for Ctrl+Space and Chinese delivered several results such as the following

that explained that Windows itself used the short-key Ctrl+Space to switch to Chinese language settings.

Since it wasn’t possible to change the language settings on all clients (it simply did not work on all) we changed the short-key for the Content Assist in Eclipse from Ctrl+Space to Shift+Ctrl+Space.

To do so, from the menu in ADT choose Window -> Preferences and then General -> Keys

Here you can change the binding from Ctrl+Space to another combination, for example Ctrl+Shift+Space

You can enter “Content Assist” as a search string. Click into the text box described with “Binding” and press the three keys Ctrl+Shift+Space. And then the button “Apply”:
