how to move temperature/heatflux on a boundary in a path: (x,y)=(0,0), (10,0), (10,1),(0,1), (0,2),(10,2) and so on,

If I understand you correctly, you are talking about setting a time-dependent boundary condition. This can be done by either entering (type them directly) the time-dependent expressions where you normally specify such boundary conditions, or by first defining time-dependent functions and then calling those functions where you specify the boundary conditions. There are also other things you can do. For example, the Comsol example application (in the Application Library) called: "Laser Heating of a Silicon Wafer," models heating from "a laser that moves radially in and out over time while the wafer itself rotates on its stage." In that model, a "Moving Mesh>Rotating Domain" is used. So you might want to take a look at that.
