For the IceCube and MAGIC Collaborations: Fourth generation neutrino telescopes are now being constructed (IceCube) and designed (KM3NET). While no neutrino flux of cosmic origin has been discovered so far, the first signals are expected to be discerned in the next years. Multi-messenger investigations aim at addressing the problem of extracting these signals from irreducible backgrounds. One application is the search for time correlations of high energy neutrinos and established signals. In this talk we show the first adaptation of a Target of Opportunity strategy to collect simultaneous data of high energy neutrinos and γ-rays. A non-established signal (neutrino) can be used to alert monitoring observations (γ-ray). In some cases the detection of positive coincidences could enhance the discovery chance. More generally the availability of simultaneous observations is increased. In case of postive detection of neutrino signals, this would allow time correlation studies and therefore constraints on the source modeling. A first technical implementation of this scheme involving AMANDA and MAGIC has been realized for few pre-selected sources in a short test run, with the aim of a feasibility study. The principles of the NToO test run and its first outcomes will be shown and the physics potential with IceCube discussed.
