Changing Home is accessed by Avatar Toolbox

This is done by clicking the little pencil icon and chose the home region you want remember to press update at the bottom of the page now your home region is made permanent or until you change the region to somewhere else, 

It is always very handy for hopping around the grid to visit regions that are further away but you DO have to log out and in again takes about 30secs to update from the webpage avatar toolbox to the viewer so you can login to the new region home you’ve selected and you can change it back if you want to another Region etc Remember you must log out and change your home region for this to work .
