How do astronauts move around when on space walks? Do they slowly make their way to their destination while keeping a harness connected to the ISS and changing the connections point as they progress?

They carry the SAFER emergency pack for case of falling off the station.
They clip themselves around the station with tethers and connection points.
The Russian segment has a couple of 'cranes' called Strela that start at the airlocks, and are telescoping poles, to make a shortcut to other modules on the Russian segment.
For larger moves around the rest of the station, there is the CanadArm2 and on the truss itself, there is a cart, that runs on a track along the truss, specifically for this purpose.
