Hitting the Return key on an attached pdf file in the presentation buffer would open the file in an external viewer.
This behavior is identical on a msword file in VM 8.2.0a. Now with VM 0.2.0b, hitting the return key on an msword attached file still invokes `vm-mime-run-display-function-at-point' but does not open the attached file in an external viewer. Instead it each times duplicates the file icon within the presentation buffer How is that so ? -- Rene
