Set period (.) NOT to use selected autocomplete item?

Hi!

I have an issue with autocomplete when typing in an attribute in an XML-document.

The problem arises when I want to type the attribute "attribute.second", and I get a list of relevant suggestions as "attribute.first", "attribute.second", and "attribute.third". When I type the period in "attribute.", autocomplete automatically inserts the selected item in the list, in this case "attribute.first".

Is there any way of disabling the period key from selecting and inserting an autocomplete item?

Thanks in advance,

Magnus
