["Ramakrishna RangaRao" <rkrangar@xxxxxxx>]

Hi All, 
 I am new to the group and pretty new to the eclipse Plug-in
development . I am writing an editor for a language called CWM . I did
some content assistance part . When I am typing '.' or '('
, I am getting the content assistance . But when I am keying down
ctrl+space , it is not workign . When I am keying down backspace ,
content assistance is popping up . Please help me with the answer or
any of the information available on net . 
Thanks very much ,
