A user is aided in using an application program. A method may include receiving an input in a computer system upon a user dropping an electronic message object in a graphical user interface of an application program. Upon receiving the input, an information portion is extracted from the electronic message object. An operation is performed in the application program with the extracted information portion as a parameter, wherein the electronic message object is not stored in association with the application program. When the performed operation includes a data repository query, a learning function or an ambiguity-resolving feature may be used.
