Search for ReSharper.ReSharper_GotoNextErrorInSolution and ReSharper.ReSharper_GotoNextHighlight and give them whatever shortcut you like. Cesar is correct with the Alt + Enter solution (ReSharper_QuickFix). Also, the navigation shortcuts he mentions are ReSharper.ReSharper_GotoNextOccurence and ReSharper.ReSharper_GotoPreviousOccurence, though those last two seem best suited for the results of Find Usages, etc.
