Method and means for establishing an activatable object in digital files. Initially, one or more search functions are defined, each linked to a processing function. Each file is investigated then on comprising one or more data elements matching with at least one of said one or more search functions and each matching data element is converted into an activatable object, linked in accordance with the relevant processing function. Files to be investigated, may be sent from a first service provider (2, 5) to the data terminal (4) of a user, said investigation being done by the first service provider or by the data terminal. The processing functions may relate to the address of a second service provider (8), fit to process the relevant matching data element. e.g. to establish a connection between the relevant telephone number, derived from the file, and the telephone number of a first user, via a telephone network.
