I think it will be very useful to allow IM query for caret location
so that candidate lookup window can be displayed near by.

Another nice feature to consider is provide a way to allow IM query
for text which has already been committed or selected.   This will help
the input method limit the number of candidates showing or list the
most likely candidate first.
