There is significant interest in the models for production of short gamma-raybursts. Until now, the number of known short gamma-ray bursts withmulti-wavelength afterglows has been small. While the {\it Fermi} Gamma-RayBurst Monitor detects many gamma-ray bursts relative to the Neil Gehrels {\itSwift} Observatory, the large localization regions makes the search forcounterparts difficult. With the Zwicky Transient Facility recently achievingfirst light, it is now fruitful to use its combination of depth ($m_\textrm{AB}\sim 20.6$), field of view ($\approx$ 47 square degrees), and survey cadence(every $\sim 3$ days) to perform Target of Opportunity observations. Wedemonstrate this capability on GRB 180523B, which was recently announced by the{\it Fermi} Gamma-Ray Burst Monitor as a short gamma-ray burst. ZTF imaged$\approx$ 2900\,square degrees of the localization region, resulting in thecoverage of 61.6\,\% of the enclosed probability over 2 nights to a depth of$m_\textrm{AB} \sim 20.5$. We characterized 14 previously unidentifiedtransients, and none were found to be consistent with a short gamma-ray burstcounterpart. This search with the Zwicky Transient Facility shows it is anefficient camera for searching for coarsely-localized short gamma-ray burst andgravitational-wave counterparts, allowing for a sensitive search with minimalinterruption to its nominal cadence.
