[jdt-ui-dev] Can't use Ctrl+Space as accelarator in my plugin

["Jens Lukowski" <jens.lukowski@xxxxxx>]

Hi
 I am coding on a XML plugin for eclipse and right now I am implementing
 a content assist processor. I want to activate it by pressing Ctrl+Space
 just like in the java editor but it doesn't work.
 Different key bindings like Ctrl+F3 or Ctrl+< work but Ctrl+Space or
Ctrl+Shift+Space
 doesn't seem to work.
 Is this intentional or is additional work necessary to support this key
binding ?
